. ‘A fuse is rated 8 A’
‘A fuse is rated 8 A’. Can it be used with an electrical appliance of rating 5 kW, 200 V?
Best Answer
The safe limit of current which can flow through the electrical appliance is I = P / V
Now,
Substituting 5 kW and 200 V in I = P / V, we get
I = P / V
I = 5000 / 200
I = 25 A
25 A is greater than 8 A.
Hence, such fuse cannot be used
