# A circuit with a resistance of 6 Omega has a fuse melts at 5 A. Can a voltage of 27 V be applied to the circuit without blowing the fuse?

It should not blow the fuse.

#### Explanation:

"Current" (I) = ("Voltage" (V))/("Resistance" (R))

In this case
$\textcolor{w h i t e}{\text{XXX}} I = \frac{27 V}{6 \Omega} = 4.5 \left(\frac{V}{\Omega}\right) = 4.5 A$(mperes).

If the fuse is rated as being able to handle up to $5 A$
this should be alright.
