Q: Kirchhoff's Current Law (KCL) is based on the principle of conservation of:

Charge — KCL states that the total current entering a junction equals the total current leaving it (conservation of charge).

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

Energy — KVL states that the sum of voltages around a closed loop is zero (conservation of energy).

Q: In a series circuit, which of the following remains constant?

Current — Current is the same at all points in a series circuit.

Q: In a parallel circuit, which of the following remains constant?

Voltage — Voltage is the same across all branches in a parallel circuit.

Q: The Superposition Theorem is applicable to:

Linear circuits only — Superposition only applies to circuits where the relationship between voltage and current is linear.

Q: What is the equivalent resistance of two 10-ohm resistors in parallel?

5 ohms — 1/R_eq = 1/R1 + 1/R2. In this case, 1/10 + 1/10 = 1/5, therefore Req=5 ohms

Q: What is the total resistance of two 10-ohm resistors in series?

20 ohms — Req = R1 + R2 = 10 + 10 = 20 ohms

Q: Which theorem is used to find the voltage across or current through a particular element in a circuit by considering one source at a time?

Superposition Theorem — Superposition allows analyzing circuits with multiple sources by considering one at a time.

Q: Thevenin's theorem simplifies a complex circuit into:

A single voltage source in series with a resistor — Thevenin’s Theorem simplifies a circuit to a voltage source and a series resistance.

Q: Norton's theorem simplifies a complex circuit into:

A single current source in parallel with a resistor — Norton’s Theorem simplifies a circuit to a current source and a parallel resistance.
