Question

If the resistance of an electric iron is 48 Ω and an electric current of 5 A is flowing through it, what will be the potential difference between two terminals of electric iron.

• A. 120 V
• B. 240 V
• C. 480 V
• D. 500 V

Answer 1

The correct option is B 240 V

According to Ohm's law:
The potential difference across a conductor is given by $V=IR$
where, $I$ is the current
and $R$ is the resistance

Potential difference between two terminals of electric iron
$V=IR$
$V=5\times 48$
$V=240V$
