Question

A current of $0.5\text{A}$ flows in a conductor of resistance $15\Omega$ . Find the potential difference across the conductor.

• A. $60\text{V}$
• B. $0\text{V}$
• C. $7.5\text{V}$
• D. $37.5\text{V}$

Answer 1

The correct option is C $7.5\text{V}$

By Ohm's law, $V=IR$
$V=\left(0.5\right)\left(15\right)$
$V=7.5\text{volts}$
