Passive Component Selection for Circuit Design Quiz…

Q: Which passive component is primarily used to store electrical energy in an electric field?

Capacitor — Capacitors store energy by accumulating charge on their plates.

Q: What is the primary function of a resistor in a circuit?

To oppose the flow of current — Resistors impede current flow, limiting the current in a circuit.

Q: Which unit is used to measure the capacitance of a capacitor?

Farad (F) — Capacitance is measured in Farads (F).

Q: What is the primary function of an inductor in a circuit?

Both a and b — Inductors store energy magnetically and resist current changes.

Q: Which unit is used to measure the resistance of a resistor?

Ohm (?) — Resistance is measured in Ohms (?).

Q: Which of the following components is NOT a passive component?

Transistor — Transistors are active components requiring external power.

Q: What determines the energy stored in a capacitor?

Capacitance and Voltage — Energy is proportional to capacitance and the square of voltage.

Q: The value of a resistor is typically indicated by:

Color-coded bands — Resistors usually use color codes for value indication.

Q: Which factor is most crucial when selecting a capacitor for a specific application?

Its voltage rating — Voltage rating must be higher than the voltage in the circuit.

Q: What is the unit of inductance?

Henry — Inductance is measured in Henrys (H).
