Question

Explain working of thermistor of and LDR
​

Answer 1

$\huge\mathbb\fcolorbox{purple}{lavenderblush}{✰Answer࿐}$

The light energy produces more free electrons which increases the current for a certain voltage across the LDR which means a drop in resistance. ... LDRs are used as light sensors. THERMISTOR. This is a type of resistor which has a resistance that changes with TEMPERATURE.

Answer 2

Answer:

"This is a type of resistor which has a resistance that changes with the amount of LIGHT that falls on it. The light energy produces more free electrons which increases the current for a certain voltage across the LDR which means a drop in resistance."
