  1. In Thevenin's theorem, the Thevenin voltage (Vth) is defined as:

    Answer: The open-circuit voltage across the terminals of interest

    Vth is the open-circuit voltage measured across the terminals after removing the load.

  2. A sinusoidal current has a peak value of 14.14 A. What is its RMS value?

    Answer: 10 A

    RMS value of a sinusoid = Peak / √2 = 14.14 / 1.414 ≈ 10 A.

  3. Which circuit element opposes a change in current?

    Answer: Inductor

    An inductor stores energy in a magnetic field and opposes changes in current through it.

  4. In the superposition theorem, when analyzing the contribution of one independent source, all other independent voltage sources are:

    Answer: Short-circuited

    Independent voltage sources not under analysis are replaced by short circuits (0 V) when applying superposition.

  5. What is the power factor of a purely inductive circuit?

    Answer: 0

    A purely inductive circuit has a 90° phase difference between voltage and current, giving a power factor of cos(90°) = 0.

  6. Norton's theorem replaces a complex network with a current source IN in parallel with:

    Answer: The Norton resistance RN

    Norton's equivalent circuit consists of a current source IN in parallel with the equivalent resistance RN.

  7. What is the unit of inductance?

    Answer: Henry (H)

    Inductance is measured in Henrys (H), where 1 H = 1 V·s/A.
