A circuit with a resistance of #6 Omega# has a fuse that melts at #8 A#. Can a voltage of #21 V# be applied to the circuit without blowing the fuse?
It works without melting.
To solve it, we apply the resistance formula:
So, we check the limit of the voltage, when Current is 8, and if the voltage is higher than 21, the circuit will work:
So, 21 < 48. It works without melting.
