Current= voltage divided by Resistance
So 8/3=2.666 amps..

Fuse is rated for 4 amps.So it is safe to apply the 8 volt supply with out blowing fuse.

A circuit with a resistance of 3 Omega3 Omega has a fuse with a capacity of 4 A4 A. Can a voltage of 8 V8 V be applied to the circuit without blowing the fuse?
