What is a likely consequence of a short circuit?

• A. The circuit becomes more efficient
• B. Wires and the cell can overheat and become damaged
• C. The current disappears immediately
• D. The battery charges faster

Answer: (B)

A short circuit creates a path of very low resistance, so current surges. With a much higher current, a lot of energy is released as heat in the wires and the cell (P = I^2R). That excess heat can cause overheating and damage to insulation, wires, and the battery. So the likely consequence is overheating and potential damage. The current doesn’t disappear, it increases, and it doesn’t improve efficiency or speed up charging.
