Question

why is black tape applied over an electric joint

Answer 1

because black tape is bad conductor of electricity and it prevents electric spark from coming out of the wire

Answer 2

Black tape is applied on electrical joints for two reasons:

1) To protect ourselves from electrical shock when current is flowing through it.

2) The most important thing is to protect it from short circuit because when both wires will come in contact with each other there will be short circuit.
