Question

Which of the following statements regarding a short circuit is true?

(a) A short circuit is a condition in which an electrical circuit allows current to flow through a path of lower resistance than intended, bypassing the normal path.
(b) A short circuit can cause damage to electrical equipment and can also start fires.
(c) A short circuit can occur when two wires with different voltages come into contact with each other.
(d) All of the above statements are true.

Answer 1

A short circuit is a condition in which current flows through a path of lower resistance than intended, causing damage to electrical equipment and potential fires. It can occur when two wires with different voltages come into contact with each other.

Step-by-step explanation:

A short circuit is a condition in which an electrical circuit allows current to flow through a path of lower resistance than intended, bypassing the normal path. This means that statement (a) is true.

Furthermore, a short circuit can cause damage to electrical equipment and can also start fires. This is due to the excessive power dissipation caused by the low resistance of the short circuit. So, statement (b) is also true.

A short circuit can occur when two wires with different voltages come into contact with each other. This leads to a sudden flow of current between the wires, resulting in a short circuit. Therefore, statement (c) is also true.

Based on these explanations, all of the given statements (a), (b), and (c) are true.
