Q: What is the primary requirement for a circuit to be considered a 'closed circuit'?

A complete path for current to flow — A closed circuit provides a continuous path that allows electric current to flow from the source to the load and back to the source.

Q: What differentiates an electronic circuit from an electrical circuit?

At least one active component — Electronic circuits must contain at least one active component (like a transistor or diode) to control the flow of electrons.

Q: In a short circuit, what happens to the resistance and current values?

Resistance is zero, current tends to infinity — A short circuit occurs when a path with zero resistance is created, causing the current to increase drastically toward infinity.

Q: Which term describes a circuit that has no return path for current?

Open circuit — An open circuit is a broken path where no current can flow because the circuit is not completed.

Q: Which of the following is an example of a technique used to solve complex electrical networks?

Thevenin's Theorem — Thevenin's Theorem is a standard method used to simplify complex networks into a simpler equivalent circuit for analysis.

Q: What is a 'node' in an electrical network?

A junction where two or more circuit elements meet — In circuit analysis, a node is a point where two or more circuit branches connect.

Q: A circuit that follows Ohm's Law and has constant parameters is defined as:

Linear circuit — A linear circuit is one where the parameters (resistance, inductance, capacitance) do not change with voltage or current, thus following Ohm's Law.

Q: What defines a bilateral circuit?

Its characteristics are the same regardless of current flow direction — Bilateral circuits allow current to flow equally well in both directions, unlike unilateral circuits like those containing diodes.

Q: Which of the following is an example of a passive component?

Resistor — Resistors, capacitors, and inductors are passive components as they do not generate energy or provide gain.

Q: A circuit containing a resistor, inductor, and capacitor is called a:

RLC circuit — An RLC circuit is an electrical circuit consisting of a Resistor (R), an Inductor (L), and a Capacitor (C), connected in series or parallel.
