What is the Difference between an Amp, Volt, and Watt

Electricity cannot be seen but it is measurable. There are quite a number of units used to measure electricity and they all represent different aspects or measurements of the electricity. However, more often than not, electric measurements are confused and used interchangeably as though they mean the same thing. Some of the most confused electrical measurements are the amp, volt and watt. If you find it difficult to distinguish between the three, this page has been made specifically for you so that you can understand the difference. Volt Volt is a measure of electricity usually referred to as voltage.

It is usually defined scientifically as the potential difference of the circuit or more commonly as the amount of pressure or force that aids in the flow of electricity in the circuit. In order to best illustrate the potential difference, you can think of two containers with water where one container is at a higher level than the other. If the two containers are connected with a pipe, water will flow from the higher container to the lower one. This is because the water at a higher level has higher potential energy. Volt is simply the unit that measures the potential energy of the flow of electrical current when electrons are being pushed around in the circuit. The parameter that is measured is known as voltage. Volt can also be equated to one joule of energy that is required to move on coulomb of electrical charge.

It is sometimes represented by the formula V = W/q where W represents the energy in joules and q is the charge in coulombs. Amp Amp is the short form of the SI unit, ampere. It is the unit that is used to measure the amount of electrical energy flowing through an electrical circuit. The name ampere is derived from the name of a French physicist by the name of Andre Marie Ampere who is considered the father of electrodynamics. Practically, amp can be defined as the amount of electric charge that is flowing through a single point in an electric circuit with 6.241 electrons per unit time. Alternatively, it can be defined as one coulomb per second. Watt Watt refers to the amount of power that is produced by an electrical circuit.

It is an SI unit named after a famous Scottish engineer by the name of James Watt. Scientifically, it is a unit of measuring the rate of energy conversion and can be defined as a unit of power with dimension in energy per unit time. According to this definition, it is simply one joule per second. Mathematically, Watt is computed by multiplying the potential difference with amount of current and it uses the formula; Watts = Volts X Amps.
