Difficulty: EasyTransistors

Match each fundamental transistor operating concept on the left with its correct electrical definition on the right.

  • AmplificationUsing a small varying input signal to control a larger output signal
  • SwitchingAlternating between full conduction and complete cutoff to control power to a load
  • BiasingApplying preset DC voltages to establish a stable quiescent operating point

Answer

Amplification matches 'Using a small varying input signal to control a larger output signal'; Switching matches 'Alternating between full conduction and complete cutoff to control power to a load'; Biasing matches 'Applying preset DC voltages to establish a stable quiescent operating point'.
Each concept pairs directly with its fundamental role in electronics: Amplification scales a small input variation into a larger output signal; Switching toggles between full conduction and total cutoff to activate or deactivate loads; Biasing establishes the necessary static direct-current voltages across terminals for stable circuit operation.

Step-by-Step Solution

1
Identify the definition of signal amplification in solid-state electronics.
Amplification corresponds to increasing signal strength by using small input fluctuations to modulate larger power supplies.
In linear active mode, transistors amplify weak audio, radio, or sensor signals.
2
Identify the functional definition of electronic switching.
Switching corresponds to toggling between saturation (closed/on) and cutoff (open/off).
Digital and power control circuits use transistors as high-speed electronic switches without moving parts.
3
Identify the purpose and definition of transistor biasing.
Biasing corresponds to setting baseline DC voltage levels at the terminals.
Proper DC bias ensures the semiconductor junctions maintain the required operational state (forward-biased base-emitter, reverse-biased base-collector).
