Question

An electric iron of 1 kilowatt is operated at 220 Volts. Find which of the following fuses respectively rated at 1A,3 A and 5A can be used in it.​

Answer 1

Step-by-step explanation:

Using I=P/V

Where I =current

P=Power

V= Potential Difference

5A can be used because we can use a fuse with higher rating.

5A = 1000/220

1100=1000

So fuse rating is higher than 1000 so we can use 5A fuse
