Question: Which analogy best represents an inductor in an electrical circuit? (2022)

Options:

Correct Answer: A flywheel

Exam Year: 2022

Solution:

An inductor can be compared to a flywheel, as it stores energy in a magnetic field and resists changes in current.

Which analogy best represents an inductor in an electrical circuit? (2022)

Step 1: Understand what an inductor is. An inductor is a component in an electrical circuit that stores energy in a magnetic field when current flows through it.
Step 2: Think about how a flywheel works. A flywheel is a mechanical device that stores energy in the form of rotational motion and resists changes in its speed.
Step 3: Compare the two. Just like a flywheel stores energy and resists changes in its motion, an inductor stores energy in a magnetic field and resists changes in the current flowing through it.
Step 4: Conclude that the analogy is appropriate. Therefore, an inductor can be compared to a flywheel because both store energy and resist changes.
