Answer 2

Name Given to Third Wire is Live Wire

Explanation:

• Three wires carry importance in any electrical circuit - live, earth and neutral.

• Electric Current is being carried by the live wire only. The circuit wire will get blasted if the wire gets connected to any part of metal accidentally, so concern goes with the protection of the user.

• The live wire carries the current to the appliance, while the neutral wire carries it back.
• The earth wire is for our protection, in case the live wire makes a contact with metal casing of an appliance.
• When this happens, the current will pass to the earth instead of our body, thus saving us.
