Two junction diodes one of germanium (Ge) and other of sillicon (Si) are connected as shown in figure to a battery of emf 12 V and a load resistance `10kOmega` the germanium diode conducts at 0.3 V and silicon diode at 0.7 V. When a 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
