PHY 102 Electromagnetic Induction 1 Objective Question
Take CBT

Question

In Faraday's experiments involving changing currents, the induced current in a secondary coil did not depend on the size of the current in the primary coil, but rather on what specific factor?
Options
A The resistance of the secondary coil.
B The rate of change of current (dI/dt) in the primary coil.
Correct Answer
C The material of the primary coil.
D The total number of turns in the primary coil.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Slide 5 states: 'The induced current does not depend on the size of the current in the right-hand coil. The induced current depends on dI/dt.'

Hint

Consider the relationship between changing current and changing magnetic flux.
