Every sensor, actuator and control unit is equipped with numerous components that are interconnected. These form electrical circuits. Many circuits consist of resistors, coils, capacitors, and transistors or FETs. The individual components can be found on a different overview page. This overview shows the circuits through which specific functions are realized. Some examples are the Wheatstone Bridge, where the change in resistance (Rx) leads to a change in the signal voltage, and the H-bridge, in which an FET circuit is responsible for controlling the electric motor.
