Question

An electrical appliance of power 2kw works at potential difference of 220v. does it require fuse of 5A give reason? and complete the questions in picture plz

Answer 1

The power of the electrical appliance = 2kw (when changed to watts it shall be 2000w)

The potential difference= 220v

Since, I=P/V, we will observe

2000/220= 9.09v

Thus, the electrical appliance requires a fuse of more than 5A else, with 9.09v the electric fuse will melt and the circuit will get broken, as it is drawing more current than its safe limit. 

Answer 2

Answer:

yes it requires the fuse

Explanation:

the power of appliance =2kw

the potential difference=220

and

I=p/v

so,

2000/200=9.09

thus the appliance required a fuse of more than 5A else with 9.09v the electric fuse will melt and the circuit will get broken as it is drawing more current than it is safe
