V I R. Wired Communications is a great source. V IR where V is the voltage across the conductor I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current.
If a voltage of 10 volts is placed across a 500 ohm resistor determine the amount of current that will flow.
Simple to use Ohms Law Calculator. We also discuss. Ohms Law is a formula used to calculate the relationship between voltage current and resistance in an electrical circuit. This reformulation of Ohms law is due to Gustav Kirchhoff.
