# A circuit with a resistance of 9 Omega has a fuse melts at 6 A. Can a voltage of 18 V be applied to the circuit without blowing the fuse?

Jan 6, 2016

Yes, its possible.

#### Explanation:

To answer, apply the resistance formula, and if $C u r r e n t < 6$, it will work without melting:
$\text{Resistance" = "Voltage"/"Current}$
9 Omega = (18 "V") /"Current"
$\text{Current" = 18/9 = 2"A}$

So, it is possible, because the current will be $2 \text{A}$.
