AC Basics: Peak, RMS & Average Values

A standard filament lamp consumes 100 W when connected to 200 V ac mains supply. The peak current through the bulb will be:

Show answer and solution

Answer: (b)

$I_{rms} = \frac{P}{V_{rms}} = \frac{100}{200} = 0.5$ A
$I_0 = \sqrt{2}\, I_{rms} = 1.414 \times 0.5 = 0.707$ A
So the answer is (b) 0.707 A.
