When an electric lamp is connected to 12V battery, it draws a current of 0.5A. The power of the lamp is:

A car headlight bulb working on a 12V car battery draws a current of 0.5A. The resistance of the light bulb is:

An inductor coil is connected to a 12V battery and drawing a current 24 A. This coil is connected to capacitor and an AC source of rms voltage rating 24 V in the series connection. The rms current through the circuit would found to be

A 250V bulb passes a current of 0.3A. Calculate the power in the lamp.

An electric bulb is connected to a 220V power supply line. If the bulb draws a current of 0.5A, calculate the power of the bulb.

An electric lamp is rated 40 W, 100 V. Find the current in the lamp and the resistance of the lamp.

A 220 V - 60 W electric lamp os connected to 220 V supply line . Determine the resistance of the lamp in incandescent state .

An electric lamp is connected with a battery of emf 10 V and it is found that 0.01A current is flowing through it. But if the lamp is connected with 220 volt mains, a constant current of 0.05A flows through it. Explain the apparent anomaly with Ohm's law.

Two electric lamps marked 110V- 60W and 110V - 100W are connected in series and the combination is connected to 220 V mains what will be efferctive power of the lamps ? What will happen due to the above connection ?

How should the several electric lamps be connected with the mains so that the switching on or off a lamp has no effect on the operation of other lamps ?
