In this HVAC training video program, Jim explains potential relays and their important numbers (1, 2 and 5) and also shows how to use a meter to test and troubleshoot them along with their companion ...

Many single-phase compressors require a start capacitor to assist in starting the motor. These capacitors will occasionally fail, causing a compressor to fail to start. Overheating is a primary cause ...

Capacitor discharge circuits are used extensively in fast pulse generation. In such applications, the capacitor's stray inductance (or equivalent series inductance) and series resistance play an ...
