Question

An electric bulb of resistance 200ohm draw a current of 1 ampere calculate the power of the bulb, potential difference at it ends and the energy in kilowatt hr consume for 5 bulbs

Answer 1

We need to find the voltage . V= IR V = 200 volts. Power = V * I = 200 * 1 = 200 w. Totally in 5 hours the power consumed Is 200 * 5 = 1000 watt hour. = 1 k w h

Answer 2

Answer:

Explanation:
