A bulb rated `60 W` at `220 V` is connected across a household supply of alternating voltage of `220 V`. Calculate the maximum instantaneous current through the filament.

A bulb is rated as 55 W and 220 volt . It is connected across the supply of 220 V- 50 Hz. Calculate (a) rms current flowing through the bulb and (b) Peak current flowing through the bulb .

Two bulbs of 60W. 220V, when connected in series with a supply voltage of 220 V, light up with maximum intensity.

If a bulb of 60 W is connected across a source of 220 V, find the current drawn by it.

A light bulb is rated 100 W for 220 V ac supply of 50 Hz. Calculate the rms current throught the bulb

A light bulb is rated at 100 W for a 220 V supply. Find (a) the resistance of the bulb. (b) the peak voltage of the source (c ) the rms current through the bulb.
