A circuit with a resistance of #6 Omega# has a fuse that melts at #8 A#. Can a voltage of #12 V# be applied to the circuit without blowing the fuse?
No, you would need a voltage of at least
We are interested here in the current, because if the current comes above a certain point the circuit will blow. The equation for current is
We know that
A current of
When current is at
for the circuit to break.
