Question
Which of the following factors does NOT directly affect the inductance of a coil?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Page 30 lists 'Factors Affecting Inductance': '1.The number of turns of the wire used in the inductor. 2.The material used in the core. 3.The shape of the core.' The applied voltage determines the current, which then leads to an induced EMF, but it is not a property that defines the inductance 'L' itself.
Hint
Inductance 'L' is an intrinsic property of the coil's geometry and material, not the external electrical conditions.
