Question

For a fuse rated at 5A, the fuse melts if the current in the circuit exceeds 5A.

• A. True
• B. False

Answer 1

The correct option is A

True

A fuse is a primary protection device against short circuits. It affords current limiting effect under short-circuit conditions. Rating of a fuse tells us the maximum current that can pass through the fuse without melting it. So, the fuse would melt if the current in the circuit exceeds 5A.
