Which of the following electronic components is classified as an active component?
Multiple Choice Options
- A
Resistor
- B
capacitor
- C✓ Correct Option
transistor
- D
inductor
Detailed Technical Solution & Explanation
An active component is a device capable of controlling the flow of electric charge, delivering electrical power, or providing signal amplification (e.g., transistors, op-amps, diodes). Passive components (resistors, capacitors, inductors) can only dissipate or store energy.
Option Analysis:
•
Option A (Resistor): Incorrect. A passive linear component that dissipates electrical energy as heat.
•
Option B (capacitor): Incorrect. A passive component that stores energy in an electric field.
•
Option C (transistor): Correct. A transistor is an active semiconductor component that amplifies and switches signals.
•
Option D (inductor): Incorrect. A passive component that stores energy in a magnetic field.
