Question

Static electricity can be generated by means of :

• A. friction
• B. electrostatic induction
• C. conduction
• D. all of the above

Answer 1

The correct option is D all of the above

Static electricity generated by rubbing one body with another suitable body is the means of friction.

When a charged body is brought very close to another neutral body, then that acquires a charge of opposite sign. This is known as electrostatic induction. If we make a direct electrical contact between a charged body and an uncharged body then charges start moving and the neutral body also acquires the same charge. This is the means of conduction.
