Question
The most important safety method used for protecting home appliances from short circuiting or overloading is:
  1. Earthing.
  2. Use of fuse.
  3. Use of stabilizers.
  4. Use of electric meter.

Answer

  1. Use of fuse.

Explanation: Use of electric fuse is the most important method used for protecting home appliances from short circuiting or overloading.

Generally, thin wire with low melting having specific rating is connected in series with the electric devices. When the current passing through the fuse exceeds a specific value then by heating effect of current it melts and breaks the circuit.
