  1. Kirchhoff's Current Law (KCL) states that:

    Answer: Current entering a node equals current leaving

    KCL: The algebraic sum of currents at any node is zero (current in = current out).

  2. Two 10Ω resistors connected in parallel have a combined resistance of:

    Answer: 5Ω

    Parallel: 1/R_total = 1/10 + 1/10 = 2/10, so R_total = 5Ω.

  3. The time constant (τ) of an RC circuit is:

    Answer: R × C

    τ = RC (resistance × capacitance) in seconds.

  4. In a series RLC circuit at resonance:

    Answer: Impedance is minimum (equals R only)

    At resonance, inductive and capacitive reactances cancel, leaving only R.

  5. Thevenin's theorem allows a complex circuit to be represented as:

    Answer: A voltage source in series with resistance

    Thevenin equivalent: open-circuit voltage source (Vth) in series with Thevenin resistance (Rth).

  6. The unit of capacitance is:

    Answer: Farad

    Capacitance is measured in Farads (F). Common values are in µF, nF, or pF.
