Ohms Law Equation

Current is measured in (A) amperes or amps.

( V or E ) Voltage is the difference in electrical potential between two points in a circuit.

It’s the push or pressure behind current flow through a circuit, and is measured in (V) volts.

( R ) Resistance determines how much current will flow through a component.

Resistors are used to control voltage and current levels.

A very high resistance allows a small amount of current to flow.

A very low resistance allows a large amount of current to flow. Resistance is measured in ohms.

( W or P ) Power is the amount of current times the voltage level at a given point measured in wattage or watts.
