Question

In an LR circuit, the AC source has voltage 220 V and the potential difference across the inductance is 176 volt. The potential difference across the resistance will be

• A. 44 V
• B. 396 V
• C. 132 V
• D. 154 V

Answer 1

The correct option is C 132 V

$TotalPD=\sqrt{P{D}_{Inductance}^2+P{D}_{resistance}^2}$
$\Rightarrow 220=\sqrt{{176}^2+P{D}_{resistance}^2}$
$\Rightarrow P{D}_{resistance}=132V$
