Question

An geyser has rating 2200W 220V on it what is the minimum setting of fuse
​

Answer 1

Explanation:

power = voltage*current

2200= 220 * I

I = 2200/220

=10 A

therefore the minimum setting of fuse should be 10 amperes

Answer 2

Answer:

Power = Potential Difference × Current

Power = 2200 W

Potential Difference = 220 V

⇒ Current = Power / Potential Difference

⇒ Current = 2200 W / 220 V

⇒ Current = 10 A

Therefore the fuse setting of the circuit must be 10 A so that, fuse breaks if current crosses this limit.
