  1. Norton's theorem converts a circuit to an equivalent:

    Answer: Current source in parallel with Rth

    Norton's equivalent consists of a short-circuit current source (IN) in parallel with the Thevenin resistance (Rth).

  2. In mesh analysis, mesh currents are defined to flow in which direction by convention?

    Answer: Clockwise

    By convention, mesh currents are assigned to flow clockwise in each mesh, though counter-clockwise is also valid if consistently applied.

  3. A 10 Ω resistor carries 2 A. What power does it dissipate?

    Answer: 40 W

    P = I²R = (2)² × 10 = 40 W.

  4. Which of the following is the correct expression for the quality factor Q of a series RLC circuit?

    Answer: Q = ωL/R

    For a series RLC circuit, Q = ωₒL/R = (1/R)√(L/C), indicating the sharpness of resonance.

  5. KVL (Kirchhoff's Voltage Law) is based on the principle of conservation of:

    Answer: Energy

    KVL states that the algebraic sum of voltages around any closed loop is zero, which is a direct consequence of energy conservation.

  6. In a purely capacitive AC circuit, current leads voltage by:

    Answer: 90°

    In a purely capacitive circuit, current leads the voltage by 90° because the capacitor charges in response to the applied voltage.

  7. What is the Thevenin resistance seen from terminals A-B when all independent sources are turned off?

    Answer: It is the resistance measured with sources replaced by their internal resistances

    Rth is found by deactivating all independent sources (voltage sources → short, current sources → open) and measuring the resistance at the terminals.
