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

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.
