Options:

Correct Answer: A river flowing back and forth

Exam Year: 2023

Solution:

Alternating current (AC) is analogous to a river that flows back and forth, as the direction of current changes periodically.

What is the best analogy for alternating current (AC)? (2023)

Step 1: Imagine a river that normally flows in one direction, like a stream moving downstream.
Step 2: Now, think about how sometimes the river can flow back upstream due to changes in the environment, like heavy rain or a dam opening.
Step 3: In the same way, alternating current (AC) changes direction periodically, just like the river can flow both ways.
Step 4: This back-and-forth flow of the river represents how AC works, as it alternates its direction of flow.

Alternating Current (AC) – AC is an electric current that reverses direction periodically, similar to the flow of a river that changes direction.
