# What are amps?

Amps, short for amperes, are a unit of electrical current in the International System of Units (SI). They measure the rate of flow of electric charge through a circuit. In electrical terms, one ampere is defined as the flow of one coulomb of charge per second past a given point in a circuit. This flow of charge, or current, is what powers electrical devices and systems by providing the movement of electrons necessary for operation.

In simpler terms, amps refer to the amount of electric current flowing through a circuit at any given moment. Just like water flowing through a pipe, electric current (measured in amps) flows through wires and components in an electrical circuit. The higher the current (in amps), the more electrical charge is flowing per unit of time.

When we say 1 amp, it means that one ampere of current is flowing through a circuit. This measurement indicates the rate at which electric charge is moving through the conductor. For instance, a device that draws 1 amp of current from a power source is consuming one coulomb of charge per second.

Amps and watts are different units used to measure different aspects of electricity. Amps measure electric current, which is the rate of flow of electric charge in a circuit. Watts, on the other hand, measure electrical power, which is the rate at which electrical energy is transferred by an electric circuit. Power (in watts) is calculated by multiplying voltage (in volts) by current (in amps). In essence, while amps denote how much current flows through a circuit, watts indicate how much electrical power is being consumed or produced.

Volts and amps are both fundamental units of electricity but measure different aspects of electrical circuits. Volts (V) measure electrical potential difference or voltage, which is the force that pushes electric charge through a circuit. In contrast, amps (A) measure electric current, which is the flow of electric charge. In simple terms, volts can be likened to the pressure in a water pipe, pushing electricity through a circuit, while amps represent the rate of flow of the electricity, similar to the volume of water flowing through the pipe. Voltage and current are interrelated in Ohm’s law, where voltage (V) equals current (I) multiplied by resistance (R), showing how these quantities interact in electrical circuits.
