Question

The current through a 12 Ω resistor in an electric circuit is 1.5 A. Calculate the potential difference across the resistor.

Answer 1

Hello!

We can use Ohm's Law to solve for the potential difference across a resistor given the current and resistance:

`V = iR`

V = Potential Difference (? V)
i = Current (1.5 A)

R = Resistance (12 Ω)

Plug in the known values and solve.

`V = (1.5)(12) = \boxed{18 V}`
