4. Receiving an electric shock from a doorknob is an example of ____________.

Explanation

Receiving an electric shock from a doorknob exemplifies static electricity. This occurs when objects build up an imbalance of electric charge due to friction or contact with other charged objects. When you touch a doorknob, the accumulated static charge on your body discharges suddenly, resulting in a brief but noticeable electric shock. Static electricity is distinct from current electricity, which involves the continuous flow of electrons through a conductor.
