Chemical effect of electric current of Class 8


We may find only two points or terminals in the plug point of our house. But they may also have three points.

The third point at the top is called the earth terminal and is connected to a thick wire that goes into the ground. Thus earthing protects us from electrical shocks. If there is any leakage of current in the appliance then it will flow through the thick wire into the earth. NCERT solutions for class 8 Science prepared by Physics Wallah will help you to solve your NCERT text book exercise.
