  1. A 10V source is connected across two parallel resistors of 20Ω and 30Ω. What is the total current drawn from the source?

    Answer: 0.833 A

    The parallel combination is (20×30)/(20+30) = 12Ω, so I = 10/12 ≈ 0.833 A.

  2. In a series RLC circuit at resonance, which statement is true?

    Answer: The impedance is purely resistive and at its minimum value

    At series resonance, inductive and capacitive reactances cancel, leaving only resistance as the impedance.

  3. What is the time constant of a series RC circuit with R = 4.7 kΩ and C = 22 μF?

    Answer: 103.4 ms

    τ = RC = 4700 × 22×10⁻⁶ = 0.1034 s = 103.4 ms.

  4. Using the superposition theorem, how are individual source contributions combined to find the total response?

    Answer: By algebraically adding the individual responses

    Superposition states that the total response in a linear circuit equals the algebraic sum of responses due to each independent source acting alone.

  5. A node in a circuit has three branches carrying currents of 3 A (in), 5 A (in), and I (out). What is I?

    Answer: 8 A

    By Kirchhoff's Current Law, currents entering a node equal currents leaving, so I = 3 + 5 = 8 A.

  6. What is the Thevenin equivalent voltage across terminals A-B if an open-circuit measurement reads 15V?

    Answer: 15 V

    The Thevenin voltage equals the open-circuit voltage measured across the terminals, which is 15V.
