A bulb of resistance `400 Omega` is connected to `220 V` mains. Calculate the magnitude of current.

How much current will an electric bulb draw from 220 V source if the resistance of the bulb is 1200 Omega ? lf in place of a bulb, a heater of resistance 100 Omega is connected to the sources calculate the current drawn by it .

An electric bulb of resistance 400 Omega , draws a current of 0.5 A . Calculate the power of the bulb and the potential difference at its ends.

An electric heater draws a current of 5 A when connected to 220 V mains. Calculate the resistance of its filament.
