# What is the relationship between Amps, Volts & Watts, and what are they?

This is a very brief guide describing Amps, Volts and Watts and how they are related in order to describe some basic electrical dependencies: Amperes (often shortened to Amps) is the standard measure of electrical current. Amps measure how much electricity is moving through a wire at any given time. The Amp draw of a circuit is dependent on the needs of the devices plugged into it, but is always limited by a branch circuit breaker. Volts are the standard measure of electrical potential and are a fixed value for every circuit. Volts are measured with respect to a reference point (usually between the two respective legs of the circuit). As one increases the electrical potential between two points, the amount of potential energy available also increases. For example, consider a stone dropped from 10 feet versus one released from 100 feet. The stone dropped from 100 feet will be going much faster when it hits the ground than one released from 10 feet and therefore will exert more energy on
