What is importance of earth wire and fuse wire in domestic electric circuit
Answers
EARTH WIRE
The connection between electrical appliances and devices with the earth plate or electrode through a thick wire of low resistance to provide safety is known as ‘Earthing’ or Grounding.
Earthing System or Grounding System in an electrical network work as a safety measure to protect human life as well as equipment, the main objective of the Earthing system is to provide an alternative path for dangerous currents to flow so that accidents due to electric shock and damage to the equipment can be avoided.
FUSE WIRE
Electric fuse is an important component in all circuits because it has a high resistivity and low melting point which melts the fuse in case of excessive amount of electricity, protecting us.
Explanation:
The main function of the earth wire is to prevent live wire from overloading and absorbs the excess electrons & flows to beneath the ground . It is necessary because it prevents the electrical appliances from damage and absorbs the excess electricity from appliances.
