What is the current in a 60.0 Ï resistor when the potential difference across it is 120.0 v?

The ohms law states that he potential difference of a current carrying conductor is proportional to the current and the resistance is constant.

therefore; mathematically; V = IR where V is the voltage, I is the current and R is the resistance in the conductor.

Making I the subject we get I=V/R

Therefore to get current we divide voltage by the resistance

I = 120 : 60 = 2 Ampheres

Therefore the current is 2 Ampheres
