The negatively charged student touches a metal tap and receives am electric shock.
explain why.

The potential difference between the student and the tap causes electrons to transfer to the tap which is earthed.

Hope this helps my sis and others

An electric shock occurs when a person comes into contact with an electrical energy source. Electrical energy flows through a portion of the body causing a shock. If you scuff your feet on your living room rug, you pick up extra electrons and have a negative charge. Electrons move more easily through certain materials like metal, which scientists call conductors. The shock he received was a result of the quick movement of these electrons.
