Question

The potential difference across wire is 75V and its electric resistance is 30Ω. Find out the electric current through the wire.

Answer 1

current = 2.5A

Step-by-step explanation:

We can use Ohm's law which states that V∝R so V=IR when the temperature is constant where V is the voltage (potential difference), I is the current and R is the resistance.

75= 30I

I= 75/30= 2.5A
