Question

germanium p-n junction diode is connected to a battery with milliammeter in series .what should be minimum voltage of battery so that current may flow?​ What happens,if the diode is now made of silicon? Give reason for your answer.​

Answer 1

Answer:

0.3 volt

Explanation:

The internal potential barrier of germanium is 0.3 V, therefore to overcome this barrier the potential of battery should be equal to or more than 0.3 V to flow current in the circuit. Therefore, the minimum voltage of battery = 0.3 V in order to flow current
