25. Which of the following can cause a short circuit?

A. When the battery runs out of electricity
B. When the insulation around a wire is frayed
C. When there is no resistor in the circuit
D. When a wire breaks



Answer :

Final answer:

A short circuit is an unintended low-resistance path that can cause damage and fire hazards.


Explanation:

Short Circuit: A short circuit occurs when there is an unintended low-resistance path across a voltage source. This can happen due to worn insulation on wires, creating a direct path with low resistance and generating excessive heat. Short circuits can lead to damage in a circuit and pose a risk of fire.
