Ohm's Law

Ohm's law states that current in a circuit is directly proportional to the voltage impressed across the circuit and is inversely proportional to the resistance of the circuit.

Current = Voltage/Resistance (I = V/R)

A voltage increases so will the current, and as resistance increases current decreases. The unit which current (I) is measured in is called Amperes (A), and the unit for resistance is ohm.
