Volts Vs. Amps: What Is The Difference

With so many of our daily use appliances running on electricity, you'll need to understand a few basic terms like voltage, current, and resistance. These are some of the essential technical terms in the electrical world that can be confusing for a layperson. Generally, a voltage is measured in volts, whereas the current is measured in amps. These terms and the relation between volts vs. amps play an essential role in understanding the flow of power in any given circuit.

Jackery Explorer 1500 Pro, Jackery Explorer 2000 Pro, and Jackery Explorer 3000 Pro are three popular home battery backup solutions with reasonable wattages. They can power most of your home or outdoor appliances for long hours. It's easy to use: all you need to do is plug the appliances into the power station and start charging. The following table reveals the battery size, capacity, rated/peak wattage, and other parameters of Jackery Explorer Portable Power Stations.

Volts Vs. Amps Facts

Before we dive deep into the differences between these electrical terms, here are a few facts about volts vs. amps.

• Amps measure the current flow, whereas volts are a measure of potential difference.
• The formula of amps is I = Q/t, whereas volts can be calculated as V = J/C.
• The simple volts vs. amps vs. wattsformula to convert volts into amps or vice versa is Watts = Amps × Volts.
• Both amps and volts are directly proportional to power.
• While amps are inversely proportional to resistance, the volts are directly proportional to resistance.

What Is Volt? What Is Amp?

Volts and amps both measure the electrical current or flow of electrons, but they do not mean the same thing. Here, we will reveal the basic amps vs. volts facts.

Voltage, also abbreviated as V or volts, represents the potential difference that exists between the two points of the conductor. It is also described as the speed of electrons when they move through a circuit.

Amperage, also abbreviated as A or amps, represents the amount of electricity that travels through the electrical system. It's the rate of current that flows through the circuit or the number of electrons that move through the wire.

Let's take an example to understand better:

Jackery Explorer 3000 Pro Portable Power Station has a battery capacity of 3024Wh rated at 70Ah. You can calculate the volts by using the simple formula:

Watt-hour = Amp-hour × Volts

Volts = 3024Wh ÷ 70Ah = 43.2V.

All the Jackery Explorer Portable Power Stations have high battery capacities (Wh) and high amp-hour ratings (Ah). These power stations or battery backups can store more power and supply steady electricity to many appliances.

Volts Vs. Amps: What Is The Difference?

There are three basic units of electricity: voltage, resistance, and current. Each of the units is measured in different ways: voltage in volts, resistance in ohms, and current in amps. In this section, we will focus on the two main units, amps and volts, and how they are different from each other.

Here's an amps vs. volts comparison table.

Definition

Amps, which is short for amperes, represent the amount of electric charge or current passing through the circuit per unit of time. The more the amps, the more electricity will flow. Volts are a bit different. It represents the electrical potential difference between two points in a circuit. The higher the volts, the more force will push the electricity through the circuit.

History

Ampere (or amps) is the SI unit for electric current and is named after Andre-Marie Ampere, a French mathematician and physicist. The SI unit for the size of the force sending the electrons through any circuit or electrical potential difference is volts, named after Alessandro Volta. He was an Italian physicist who created the inverter of the electric battery.

Voltage & Current & Power

Watts (power), volts (voltage), and amps (current) are related as follows:

W = V * A

Power is directly related to current (A) and voltage (V). Imagine you are spraying the hose to turn a water wheel. The faster the wheel will turn, the more power will be generated. If the hose size remains the same, you can either increase the flow rate or the water pressure to turn the wheel faster. In this analogy, the water pressure represents the voltage while the water flow rate is equivalent to the current.

Relationship with Resistance

Amps, resistance, and volts are related quantities. The term "resistance" measures how difficult it is for electrons to pass through the circuit. If the amps measure the water flowing through a pipe and resistance is the length and diameter of the pipe itself, then the volts represent the water pressure in the pipe.

Ohm's law defines the relationship between amps, volts, and resistance. It states the current flowing through the circuit is directly proportional to voltage (or volts) and inversely proportional to the resistance (measured in ohms) of the circuit.

I = V/R

If the voltage is 4V and the current is 2A, the resistance in the circuit will be calculated as R = 4V/2A = 2 ohms.

Direction of Flow

Another critical difference between volts vs amps is the direction of current flow. The electron current typically flows from the negative terminal of any voltage source to the positive terminal. Generally, the current flows from higher potential to low potential levels. On the other hand, voltage does not have any direction of flow. It typically represents the difference in electric potential between two ends in the circuit.

What Is Volt-Ampere?

Volt-amperes measure the "apparent" electrical power that's calculated by applying voltage by amperage. The term is often used to simplify power ratings, determining how much power the current will draw while using. Similarly, watts is the rate at which energy is either generated or consumed and is derived by multiplying voltage and amperage.

While both volt-ampere and watts derive from multiplying voltage by amperage and measuring electrical power, the underlying concept is distinct. The primary difference between the two is that the VA measures "apparent power," which defines how much electrical power the current will draw once it is active, whereas watts indicate the "real power," which determines how much energy is consumed or generated.

Volts Vs. Amps FAQs

How many volts are in an amp?

One amp is the amount of current when 1 volt of electrical pressure is applied against 1 ohm of resistance.

How many amps are in a volt?

A volt is the unit of the electric force or pressure that causes electricity current to flow in a given circuit. One volt is the pressure that can drive 1 ampere of current flow against 1 ohm of resistance.

Are volts more powerful than amps?

If the voltage is higher, more power will flow into a device without needing as many amps flowing out of the main circuit breaker panel.

What is the difference between volts and amperage?

Both volts and amperage measure electricity. A volt is the size of the force that sends the electron through a circuit or a unit of electric potential difference. On the other hand, an ampere is the unit that measures electric current.

What devices are used to measure volts and amps?

A multimeter (also called VOM, volt-ohmmeter, or volt-ohm-milliammeter) allows you to safely measure voltages, amps, and other electrical units. A multimeter can be used to calculate current, voltage, and resistance, which is why it can be used as an ohmmeter, voltmeter, and ammeter.

Final Thoughts

Amps and volts are essential units that determine how much energy or power can be delivered to an electrical device or any circuit. Without sufficient amps value, there would not be enough energy available for a device to function appropriately. Similarly, if there is not enough voltage available, the device will not be able to push the required amount of energy through a conductor.

As discussed in this volts vs. amps guide, they both go hand-in-hand. Jackery Explorer Portable Power Stations have enough wattage, amps, and volts to make them ideal for charging small and large appliances. The largest and most powerful Jackery Explorer 3000 Pro Portable Power Station can charge 99% of appliances, making it an excellent choice for indoor and outdoor use.
