PCB Component Identification and Function Quiz…

Q: Which component is typically 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 the flow of current, thus controlling the circuit's current and voltage.

Q: Which component is commonly used for switching or rectification in electronic circuits?

Transistor — Transistors act as switches (on/off) or amplifiers. Diodes also rectify.

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

To oppose changes in current flow. — Inductors resist changes in current due to the magnetic field it generates.

Q: What is the primary function of a diode?

To allow current flow in one direction and block it in the other. — Diodes conduct in one direction (forward bias) and block in the other (reverse bias).
