### An example of Electro Static Discharge or ESD is the zap one sometimes feels after walking across carpeting and touching a metal doorknob

• A.

True

• B.

False

A. True
Explanation
Electrostatic discharge (ESD) occurs when there is a sudden flow of electricity between two objects with different electrical charges. In this example, when someone walks across a carpet, their body accumulates static electricity. When they touch a metal doorknob, the excess charge is discharged, resulting in a small shock or "zap" sensation. This phenomenon is a common occurrence and is indeed an example of electrostatic discharge.

### Static Charges are generated all the time when two surfaces contact and separate. Electrons move from one surface to another causing an imbalance. The Surfaces with a defiency of electron has a positive charge and the surface with an excess of electrons has a negative change

• A.

True

• B.

False

A. True
Explanation
Static charges are generated when two surfaces come into contact and then separate. This movement of electrons causes an imbalance, resulting in one surface having a positive charge (deficiency of electrons) and the other surface having a negative charge (excess of electrons). Therefore, the statement is true.
