Question

1. The mains power supply of a house is through a 2A fuse. How many 50W bulbs can be used in this house at the normal voltage?
PLZ FAST ONLY ANSWER .....​

Answer 1

Answer:

Suppose x number of such bulbs can be used

Power of one bulb = 100 watt

Power of x bulbs (p) = 100 X x watts

Potential difference (V) = 220 volts

I = 5 ampere

We know that P = VI

100 X x = 220 x 5

x = 220 x 5 /100 = 11 bulbs
