Suppose you acquire a positive charge from walking across a carpet. you then touch a doorknob and receive a shock. this leaves you

a.
positively charged
b.
negatively charged
c.
electrically resistant
d.
electrically neutral

d.

electrically neutral

Explanation:

At the beginning, after you walked across the carpet, you gain positive charge because electrons flow from you to the carpet, leaving you with an excess of protons compared to the electrons.

When you touch the doorknob, the electrons in the doorknob are attracted by the excess of positive charge (the protons in excess), so they start flowing from the doorknob towards your body: this is the electric shock that you feel.

The electrons will flow towards your body until they completely neutralize the excess of positive charge that you initially had; therefore, at the end of the shock, there will be no excess of positive or negative charge, so you will be electrically neutral.

option (d) is correct.

Explanation:

Your body is positively charged and you touch the metal knob of door.

Metal is the good conductor of electricity, so it can flow the charge from your body which makes your body discharged and you become electrically neutral.
