Which of the following circuits will still be dangerous even if the fuse blows off and electric iron stops working during a short circuit?
"\n
Circuit (B) will still be dangerous even if the fuse blows off and electric iron stops working during a short-circuit.
The reason for this is that the live wire that carries A.C. the power it is still in contact with the electric iron. Whereas Circuit A is not dangerous even if the fuse blows off because the fuse is fitted in the live wire and due to this its contact with the electric iron stops.
