A 110 W, 220 V bulb draws a current

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.

A 25 W , 220 V bulb and a 100 W , 220 V bulb are connected in parallel across a 440 V line

Calculate the resistance of a bulb rated 100 W, 220V. What is the current flowing in the bulb when connected across a potential difference of 220 V?

A 25 W, 220 V bulb and a 100 W , 220 V bulb are connected in series across a 220 V line , which electric bulb will glow brightly?

A 25 W, 220 V bulb and a 100 W , 220 V bulb are connected in series across a 220 V line , which electric bulb will glow brightly?

100 W, 220 V bulb is coonected to 110 V source. Calculate the energy consumed (in unit of electricity) by the bulb in 1 hour.
