A circuit with a resistance of #6 Omega# has a fuse that melts at #8 A#. Can a voltage of #45 V# be applied to the circuit without blowing the fuse?

Current in circuit= voltage divided by Resistance
Voltage =45 resistance=6 ohms. So current is 45/6=7.5 amperes..
Rating of fuse 8 amperes.Actual current only7.5 amps.So it is safe.Fuse will not blow off.
