How much current will an electric heater coil draw from a 220 V source, if the resistance of the heater is 100Omega ?
How much current does an electric heater draw from a 220 V line, If the resistance of the heater (when hot) is 50 Omega ?
An electric bulbs draws 1.2 A current at 6.0 V . Find the resistance of the bulb.
An electric bulb is rated 60 W , 220 V . The resistance of its filament is
A light bulb is rated at 100 W for a 220 V ac supply . The resistance of the bulb is
An electric bulb is rated at 220V, 100W. What is its resistance?
A bulb of 40 W is connected across a source of 220 V . Find the resistance of the bulb.
An electric bulb is rated as 220 V-55 W. find the value of its resistance.
A torch bulb when cold has 1 Omega resistance. It draws a current of 0.3 A when glowing from a source of 3 V . Calculate the resistance of the bulb when glowing and explain the reason for the difference in resistance.
