What principle do synchros operate on?

Synchros operate on the principle of electromagnetic induction. This principle involves the generation of electromotive force (emf) in a coil or circuit due to a changing magnetic field. In the case of synchros, they utilize this principle to convert angular position into an electrical signal.

Specifically, synchros are devices that sense the position of a rotating shaft and transmit this information to control devices or other systems. When the rotor of a synchro, which is typically an electromagnetic component, spins in a magnetic field created by the stator, it induces an electrical current in the windings of the rotor. This induced current generates a voltage that is proportional to the angle of rotation of the rotor.

The ability to produce a unique electrical signal based on angular position is fundamental to the operation of synchros, enabling them to be used in various applications such as navigation systems, automatic control devices, and remote sensing equipment.

The other options relate to different electrical principles that do not apply to synchros: capacitance involves the storage of electrical energy in an electric field, inductance deals with energy storage in a magnetic field, and resistive heating refers to the generation of heat in a conductor when electrical current passes through it. These principles do not encompass the
