0.7V
0.3V
1 V
2 m V per degree Celsius E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is A. 0.7V.
A silicon diode is a semiconductor device that allows current to flow in one direction only. The barrier potential is the voltage difference between the two terminals of the diode
when no current is flowing. The barrier potential of a silicon diode at room temperature is 0.7V.Option B is incorrect because the barrier potential of a silicon diode is not 0.3V.
Option C is incorrect because the barrier potential of a silicon diode is not 1V.
Option D is incorrect because the barrier potential of a silicon diode is not 2 m V per degree Celsius.
Option E is incorrect because the barrier potential of a silicon diode is 0.7V.
