A fuse is used in an electric circuit to

Options

  1. Abreak the circuit when excessive current flows through the circuit
  2. Bbreak the circuit when power gets off
  3. Cindicate if the current is flowing uninterrupted
  4. Dcomplete the circuit for flow of current

Correct answer

A. break the circuit when excessive current flows through the circuit

Step-by-step solution

Fuse is a conducting wire of high resistance and low melting point so that when a large current passes through it, it melted down and protect the circuit or electric appliance from damage.
