# A circuit with a resistance of 3 Omega has a fuse with a capacity of 4 A. Can a voltage of 12 V be applied to the circuit without blowing the fuse?

##### 1 Answer

Current= voltage divided by Resistance 12/3=4 amperes..

#### Explanation:

Fuse will blow at 4 amps. This is a just rated amps for the fuse..It may not blow at rated amps but it is risky as any slight increase will blow fuse.
