Answer 1

Explanation:

Given,

w=2000

v=220

we know,w=vi

=i=w/v=2000/220=9.09A

current drawn is 9.09A

hence the fuse wire should be at 10A for safe use with this geyser

Answer 2

Answer:

Given

Power=2000w

Voltage=220

I=?

P= v*I

I=P/v

=2000/220

=9.09 amp

Fuse rating should be greater than flowing current .

Hence select a fuse of 10 amp
