Checking value / voltage of earthing in home electrical socket is very easy. We can check if earthing is proper or not using a Test Lamp or a Multimeter. Let us learn in detail.

#What is a Multimeter?

A Multimeter is a measurement instrument designed to measure electric current, voltage, and resistance over several value range.

How to Check Earthing at Home with a Test Lamp

1. Insert the Positive Wire of the Test Lamp in the Positive side (Right Hole) of the Socket and Negative Wire to the Negative side of the Socket (Left Hole).
2. Switch ON. The Bulb will Glow at Full Brightness.

2. Insert the Red Probe in the Positive Hole of the Socket (Right Home) and the Black Probe in the Negative Hole of the Socket (Left Hole).
3. Check and Note down the value.
4. Now Remove the Black Probe and insert in the Earthing Hole of the Socket.
