What electrical principle is used by a wheel speed sensor in an ABS system?

A) three-wire voltage divider
B) pulse generator
C) thermistor
D) variable capacitance sensor

Electrical Principle

Fundamental laws or concepts in electricity, such as Ohm's law, which govern the behavior and operation of electrical systems and components.

Wheel Speed Sensor

Reluctor-type electromagnetic device used to signal wheel speed data to an antilock controller. Consists of a permanent magnet and toothed reluctor. As the reluctor wheel cuts through a magnetic field, AC is generated and a frequency signal produced.
