Explain the importance of Earthing and also Explain how Earthing is done.
Answers
One of the most important reasons for grounding electrical currents is that it protects your appliances, your home and everyone in it from surges in electricity. If lightning was to strike or the power was to surge at your place for whatever reason, this produces dangerously high voltages of electricity in your system. If your electrical system is grounded, all of that excess electricity will go into the earth — rather than frying everything connected to your system
Importance and working of Earthing.
Explanation:
Earthing is a wire used during wiring of the house that allows the power exchange in your home to operate safely.
There is no electronic damage incurred when used. And the body does not suffer any shock after touching any saline device.
The earthing ie the cover of the ground wire is green.
220v ac is given as power to any equipment that works in electricity. It has a connection wire to connect all the equipment to the power board. And the current reaches that device through that wire. But to connect this wire to the power board, it also has a power plug which is placed in the socket of the board.
If you have used such electric equipment, then you must have noticed that the connection of any equipment is only 2 pins in the plug of the wire, then there is also 3 pins in the plug of any equipment.
The 3 pin electric equipment plug has 2 connection pins only for the input supply, but the third pin at the top is the one that is pinned for the earthing connection. Just like that in the iron power plug There are also 3 pins, out of which the top pin is only for ground wire connection. The earthing pin is connected to the cabinet of any equipment.
