What are the types of potentiometers?

A potentiometer is a three-terminal resistor with either rotating or sliding contact that forms an adjustable voltage divider. On the basis of the movement of the wiper, potentiometers are divided into two main types which are further classified as:

Rotary potentiometers

Concentric potentiometer

Single-turn potentiometer

Servo potentiometer

Linear potentiometers

Multi-turn slide potentiometers

Slide potentiometers

Dual-slide potentiometers

Two parallel plate capacitors X and Y are connected in series to a 6 V battery. They have the same plate area and same plate separation but capacitor X has air between its plates, whereas capacitor Y contains a material of dielectric constant 4. Calculate the capacitances of X and Y, if the equivalent capacitance of the combination of X and Y is \( 4 \, \mu\text{F} \). Calculate the potential difference across the plates of X and Y.
