It is known that when working with an electrical appliance then your hands must be dry because otherwise an electrical shock might occur.
Water is a good solvent and electrons can flow through it easily. Also, your work station must be dry also as it might also lead to an electrical shock.
Your plug must be pull on because otherwise some amount of electric current will still flow into the circuit. And, there are chances of getting an electric shock.
Hence, we can conclude that actions which are appropriate and safe when working with electrical equipment are as follows.
Answer: Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
