Example for wiper, a bus or a 4 wheeled vehicle has a wiper used to remove the rain droplets on the screen, wiper is attached to potentiometer.

Rheostat has only two terminal. How can you say it has three terminal @Saurav Raj?

A wiper is the sliding contact in a Potentiometer.

Rheostat has three terminal then how can its possible?

Wiper is a sliding contact in a potentiometer.

Potentiometer is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider, current divider or other devices. Thermistor is a type of resistor whose resistance varies significantly with temperature.

Can any one explain about the wiper?

Rheostat have three terminals. One variable, 2 fixed terminals. Then how it can be rheostat?

Sravani said:   1 decade ago
Wiper is nothing but potentiometer which we can adjustable the resistance value. Where as rheostat is a variable resistance.

Please anyone give difference between them i.e. Rheostat, Wiper, Thermistor, Potentiometer?
