Question 50
ElectronicsI. For current amplification II. For voltage stabilization
III. For power amplification IV. As a switch.
Which of the above are the uses of a transistor?
- A.I,II,III and IV
- B.I,III and IV only
- C.I,II and III only
- D.I,II and IV only
Show the answer and explanation
Answer: B (I,III and IV only)
Explanation
A transistor can amplify current and power and can act as a switch (I, III and IV). Voltage stabilisation (II) is done by a Zener diode, not listed as a transistor use.
