Question

Choose the statement which is not correct about an electric fuse.

• A.
  Fuses are inserted in electric circuits to prevent damage to the circuits.
• B.
  There is a maximum limit on the current which can safely flow through the electric circuits.
• C.
  There is a minimum limit on the current which can safely flow in the electric circuits.
• D.
  If a proper fuse is inserted in a circuit it will blow off if current exceeds the safe limit.

Answer 1

The correct option is C

There is a minimum limit on the current which can safely flow in the electric circuits.

A fuse is a safety device which limits current in the circuit and, as a result, prevents electrical circuits from getting damaged.​ In the case of an electric fuse, there is only a maximum limit on the current which can safely flow in the electric circuits.
