A circuit with a resistance of $6\mathrm{\Omega}$ has a fuse that melts at 8A. Can a voltage of 42V be applied to the circuit without blowing the fuse?

First, we need to find the voltage at which the fuse melts.

Thus, we use Ohm's law here, which states that

V=IR

The fuse melts at 8A with a resistance of $6\mathrm{\Omega}$ , so we must plug in those values into the equation.

We get:

$V=8A\ast 6\mathrm{\Omega}$

=48V

So, the fuse will melt at 48V or more.

Since 42V < 48V, then the fuse will not melt when a voltage of 42 volts is passed through it.

So, a voltage of 42V can be applied on the circuit without blowing the fuse.
