(a) In the following diagram 'S' is a semiconductor . Would
you increase or decrease the value of R to keep the
reading of the ammeter A constant when S is heated ?
Given reason for you answer .
(b) Draw the circuit diagram of photodiode and explain
its working . Draw its I-V characteristics.

Text Solution

Verified by Experts

On heating S, resistance of semiconductors S is decreased so to compensate the value of resistance in the circuit R is increased.
