Chapter 23, Problem 69A

To determine

To Explain: A short circuit and the way it is dangerous.

Explanation of Solution

Introduction:

A short circuit in an electric circuit is a path with very low resistance.

As the resistance in the short circuit is very low, a large amount of current flows through itwhich heats up the wire and can catch fire. Also as a large amount of current is drawn, it may cause damage to the power source.

Conclusion:

A short circuit is a very low resistance path which draws a heavy current causing damage to the wires and power source.
