The minimum potential difference between the base and emitter required to switch a silicon transistor ON is approximately?

A

`1V`

B

`3V`

C

`5V`

D

`4.2V`

Text Solution

Verified by Experts

The correct Answer is:
a
To switch on the transistor, the emitter-base junction of a transistor is forward biased while collector-base junction is reverse biased. The cut-off voltage for silicon is `~1 V`, so the swith on a silicon transistor a potential difference of `1V` approximately is required between the base of emitter.
