Question

Difficulty: EasyTransistors

A transistor can use a small electrical signal at one terminal to control a much larger current flowing through its other terminals.

Answer: Answer

Answer

True
The statement is true because the defining characteristic of a transistor is its ability to govern a large current path using a relatively weak electrical control signal, making it effective for both amplification and switching.

Step-by-Step Solution

1
Identify the primary operational functions of a transistor in electronic circuits.
Transistors are solid-state components designed to act as electronic switches and signal amplifiers.
Recalling the basic definition and purpose of semiconductor devices establishes the core functional criteria.
2
Evaluate the relationship between the input control signal and the output circuit current.
Applying a relatively small signal to the control terminal modulates and directs a much larger current between the power terminals.
This control mechanism allows small electronic signals to switch heavy loads on or off and amplify weak audio or radio signals.
