Question

How much is the intensity of electric current in a circuit whose potential difference is 18 volts and has a total resistance of 3 ohms?

Answer 1

Potential difference : (V) 18 v

Resitance = (R) = 3 ohms

Apply Ohm's law:

V = I * R

I = V / R

replacing:

I = 18/3 = 6 ampere

Answer : 6 A
