Which of the following statements are true for inductors. Select one or more: a. An inductor connected to a capacitor acts as a resonator for oscillating current. b. Inductors have non-zero internal resistance. c. Inductors in circuits act to resist changes to the current. d. An inductor is a wire that is wound into a coil. e. The inductance is measured in the unit Henry (H).

00:01 Hello, it is mentioned in the question that we have to identify which statements about the inductor are true.

00:05 Let us consider bit a of the question.

00:08 The first statement is true.

00:10 This is because an inductor connected with the capacitor acts as a resonator for oscillating current.

00:15 And we can explain this by considering that the electrical energy stored in the capacitor is converted to magnetic energy of the inductor and vice versa and thus the energy keeps on oscillating between the inductor and capacitor and this oscillation is maximum at a particular frequency the omega thus inductor connected with capacitor x as a resonator for oscillating current.

00:33 Let us consider b bit of the question.

00:34 In the b bit of the question that statement is also true.

00:39 To understand why it is true, let us consider the inductor.

00:41 Inductor has an impedance of xl is equal to 2 pi new l.

00:45 That is xl, the impedance of the inductor is equal to 2 pi new l.

00:50 Here new is the frequency of the current, the frequency of current and l here is the inductance of inductor.

01:06 Thus, the inductor have a non -zero resistance.

01:10 So the second statement is also true.

01:12 Let us consider the bid c of the question.

01:15 The bid c of the question is also true.

01:16 Since inductor have a non -zero resistance, they resist a change in the current.

01:21 So that is also true...
