Photo Resistor-Light Dependent Resistor

Some resistors are dependent on physical quantities like light, heat, magnetic force, etc. These resistors can be divided into 4 types which includes: • Photo resistor (LDR) • Thermistors (NTC and PTC) • Varistor (VDR) • Magneto resistor (MDR)   Photo Resistor Photo resistor is an electronic component whose resistivity…

Potentiometer:A Type Of Variable Resistor

A Variable resistor is a resistor that does not have fixed value of electrical resistance, that is the value of electrical resistance can be varied or adjusted.. Variable resistor can be divided into 3 types, they are: Potentiometer Rheostat Trimpot Potentiometer A potentiometer is a 3 terminals variable resistor which…
