Two junction diodes, one of germanium (...

Two junction diodes, one of germanium `(Ge)` and other of silicon `(Si)` are connected as shown in fig to a battery of `12 V` and a load resistance `10 kOmega`. The germanium diode conducts at `0.3 V` and silicon diode at `0.7 V`. When current flows in the circuit, the potential of terminal `Y` will be
.

A

12V

B

11V

C

11.3V

D

11.7V

Text Solution

Verified by Experts

The correct Answer is:
D
After a 0.3 volt drop across Ge diode. It will start conducting
output `=12-0.3 =11.7 V`
