# A circuit with a resistance of 6 Omega has a fuse that melts at 8 A. Can a voltage of 28 V be applied to the circuit without blowing the fuse?

Yes,a voltage of 28v can be applied to the circuit without blowing fuse since current flowing through fuse is 4.67A where as rating is 8A.

#### Explanation:

From Ohm's law,

$V = I R$

$I = \frac{V}{R}$

Given that, $V = 28 v \mathmr{and} R = 6 o h m$

$\implies I = \frac{28}{6}$

$\implies I = 4.66666 A < 8 A$
