Rotational Speed

The number of rotations per unit time, usually measured in revolutions per minute (RPM).

Voltage Generated

The production of electrical potential difference between two points in a circuit, often as a result of chemical reactions within batteries or by electromagnetic induction.

Wheel Speed Sensor

A sensor used in vehicles to measure the speed of a wheel, crucial for the proper functioning of systems like ABS (Anti-lock Braking System).
