The correct answer is: a) the electrons flow from the doorknob to your hand and you feel a shock When you walk on a carpet, you gain a positive charge by losing electrons. When you touch the neutral doorknob, electrons from the doorknob flow into your positively charged hand to balance the charge, causing a sudden discharge—this is the shock you feel. |
