Which terminals are present on a single phase compressor?

In a single-phase compressor, the presence of start, run, and common terminals is essential for its operation. The start terminal is used to provide the necessary boost of electrical energy to begin the compressor's operation. This terminal connects to a start winding within the motor that momentarily increases motor torque, helping to initiate the compressor's mechanical movement.

The run terminal, on the other hand, is associated with the run winding, which keeps the compressor operating after the start winding has fulfilled its purpose. Once the compressor reaches a sufficient speed, the circuit is designed to disconnect the start winding, allowing the compressor to run solely on the run winding.

The common terminal serves as a shared connection point for the windings, completing the circuit for both the start and run windings. This structure is vital for the compressor's functionality, ensuring that it can efficiently start and remain operational throughout its use.

The other options do not accurately reflect the typical configuration found in single-phase compressors, as they either include incorrect terminal types or terminology not commonly associated with compressor operation.
