A circuit with a resistance of #6 Omega# has a fuse that melts at #8 A#. Can a voltage of #42 V# be applied to the circuit without blowing the fuse?
Yes, it can be applied.
First, we need to find the voltage at which the fuse melts.
Thus, we use Ohm's law here, which states that
The fuse melts at
So, the fuse will melt at
So, a voltage of
