You can convert VA to amps by using the watts law formula of power, which is W = V x A, and by rearranging the formula, you can convert apparent power to current. For example, in a single-phase circuit, with 1000 volt-amp of power and at 100 volts, the current will be:
I(A) = S(VA) / V(V) = 1000VA/ 100V = 10A
In electrical devices, the VA value simplifies the power rating and helps to measure the reactive power needed in capacitors and inductors. VA and ampere significantly determine the correct wire size, circuit breaker, and energy cost estimation.
Jackery Portable Power Stations are battery-powered solar systems with high capacity and Ah to power most of your devices. These use solar energy and convert it into electrical energy to use it as a backup. The power stations are portable and lightweight, so they can be carried out easily for outdoor adventures as well.
Key Takeaways
- Three fundamental units of measuring electricity are voltage, power, and wattage.
- VA is the apparent power, and W is the true power, which is equal in DC circuits.
- The selection of a suitable circuit breaker can help avoid overheating.
- The three-phase formula is the square root of three times the line-to-line voltage of the circuit.
What Are The Amps, Volts, and Watts?
Ampere, wattage, and voltage are the three fundamental units of measuring electricity that explain electricity flow and consumption. When talking about pressure while looking at the electrical circuit, it denotes the voltage. Voltage is small charges inside the wire throughout the circuit, and when applied from one side of the wire, it pushes the electricity through the circuit. It is also known as the change in pressure or potential difference. Voltage is represented with a V when used for electrical equations.
The current flow in an electric circuit from one point to another is known as amperage. Through an ampere-hour calculator or a power consumption calculator, ampere forms the basis of scaling your solar power system. If you consider coulombs to work with, one ampere equals one coulombs. Ohm's and Watts's law shows the relationship between ampere and volts.
Wattage is the unit of power that describes the rate at which work is done on an object. It is also defined as one joule of work on an object per second.
Wattage is the multiplication of voltage and ampere that is W = V x A. This law represents three different power units in a triangle where wattage is at the top, ampere at the bottom, and voltage at the bottom. You can divide or multiply two remaining units for a specific unit, like dividing watts by voltage to get ampere.
What Are The VA (Volt-Amps)?
In a direct current (DC) electrical circuit, volt-ampere is the power measurement, and its specification is also used in alternating current circuits. In the latter case, it represents apparent power represented in VA, which differs from true power expressed in watts. Apparent power (VA) and true power (W) are equal in DC circuits. VA represents the energy a device consumes or draws from the circuit.
VA and power mean the same thing in AC circuits with no reactance. Reactance happens when a circuit has a capacitor or inductor. VA is greater than the delivered power in watts in circuits with reactance. This is why volt-amperes is the apparent power and a power supply with a volt-ampere value delivers lower actual power.
In devices such as UPS, the VA value of apparent power simplifies the power ratings of the current drawn-in devices. The value derived by the calculations helps determine what kind of circuit breaker is required for electronic devices. To avoid problems during electrical surges, the power supply rating should be higher than the equipment. A volt-ampere specification also helps to measure the reactive power needed in capacitors and inductors to create magnetic and electrical fields.
How to Convert VA to Amps?
Wattage is calculated by multiplying voltage with amperes, and for your desired kilowatts, calculating the correct wire size is essential for preventing overheating and fire hazards. A deeper electrical comprehensive can be understood by understanding the relationship between KW and ampere, which is vital to ensuring the safe operation of electrical devices. The relationship between kW and ampere is essential to determine the correct wire size, choose a circuit breaker, and estimate energy costs for efficient usage.
Selecting the correct circuit breaker lets you know the ampere that the circuit draws to avoid overloading. The current drawn estimation also helps you to estimate your electricity plan. Converting VA to ampere can be a reliable sidekick while designing a solar panel system or fixing household circuits.
A volt-ampere (VA) measures the apparent electrical power, while an ampere measures the electrical current. The conversion between them includes Watt’s law formula of power. It states that the power is equivalent to voltage multiplied by current. By rearranging the formula, you can convert the apparent power (VA) to current (A):
I(A) = S(VA) / V(V)
For example, in a single-phase circuit, with 2000 volt-amp of power and at 150 volts, the current will be:
I(A) = 2000VA/ 150V
I(A) = 13.33A
For a three-phase electrical circuit formula, the volt-amp to amp conversion, the modified three-phase formula is:
I(A) = S(VA)/√3 × VL-L(V)
Here, the current (A) is equal to the apparent power (VA) divided by the square root of three times the circuit's line-to-line voltage.
For example, the current for a three-phase electrical circuit with 40,000 volt-ampere of power at 500 volts will be,
I(A) = 40,000VA / √3 × 500V
I(A)= 40,000VA / 1115V
I(A)= 35.87A

How to Convert Amps to VA?
The apparent power (VA) is given when the watt rating is absent and is used to simplify power ratings. By converting amps to VA, you can determine the power required for your electronic devices. The actual power is not always equal to the VA rating; therefore, the VA rating should be heeded. The power supply must have a higher rating to lower the risk of electrical surges.
The conversion of amps to VA is done by using the Watt’s law formula of power,
P = V x I
The amps-to-volt-amp formula can be derived by arranging these variables with amps, volts, and volt-amps,
S(VA) = V(V) × I(A)
For example, for a single-phase circuit with a current of 15 amps at 150 volts,
S(VA)= 150V x 15A
S(VA)= 2250VA
For a three-phase electrical circuit, the formula used will be:
S(VA) = √3 × VL-L(V) × I(A)
For example, the amps for a 580 volts three-phase electrical circuit with 62 amps of current will be,
S(VA) = √3 × 580 V × 62 A
S(VA) = 62282VA.

Why Do VA Ratings Matter in A Battery?
An electronic device relies on the battery for power, and there is no way to neglect choosing the correct device battery to get a smooth supply of energy to run your essential appliances. An ideal device battery capacity depends on power requirements, VA rating, and backup hours. The backup hours are when you want a device to supply power during an outage. For example, if you want a backup for 4 hours, you can multiply the power requirement by four.
The voltage of a battery does not determine the ampere, but rather, it determines how much current will flow through a resistance. It determines the push a battery can give. The current rating determines how much current the battery can deliver without causing damage. A battery will not work if supplied with a low voltage; hence, it won't be able to power lights, radios, and computers, and if the voltage is high, it will damage the electronics.
Ah rating is calculated by adding the individual rating and multiplying the individual rating of the cells by the cell count. Other values help give an idea of what to expect in a battery and represent its capability more accurately. For example, the C-rate represents the battery's ability to charge and discharge, and for that, you can refer to charts and formulas to get the C-rate on a battery.
Amp-hours (Ah) is a unit used to measure the energy capacity of a battery. It tells how much current a battery can provide at a specific rate over time. For example, if you have a 6-Ah battery, it can provide six amps of current per hour. But if your device needs one ampere of current, the total charge would last six hours. Factors affecting how long the Ah will last include charging and discharging the battery, battery age, ambient temperature, etc. In solar power systems like the Jackery Portable Power Station, you can store electrical energy in the battery for further use when charging the devices.
