Thermistor

A thermistor is a type of resistor whose resistance changes rapidly with temperature. The word 'thermistor' is derived from "thermal" and "resistor". They are temperature sensors.

Light Dependent Resistor

What is LDR

Light dependent resistor is also referred to as photo-resistor, cadmium sulfide (cds) cell, photoconductor or photocell. It is an electronic component whose resistance changes with the light intensity falling on it. It has the ability to detect the presence or absence of light and this detection reflects on its resistance value.This allows them to be used in light sensing circuits. Their ability to produce a very large change in

Resistor Basics

Resistor is an electronics component that offers opposition to the flow of electrons. This resistance have a specific electrical resistance. Resistors are primarily used for current limiting, voltage division and similar functions.

The resistance of a resistor is measured in ohms using the Greek symbol omega (Ω).
