This consists of understanding the operation of all the components that are used in the circuit. This could include such components as: push buttons, contactors, various types of switches, relays, sensors, motors, etc. Electrical circuits typically control or operate mechanical systems and components. You also need to understand how these mechanical aspects of the equipment operate to carry out the work. You need to be able to determine how the circuit works under normal conditions and what effect changing one of the circuit inputs has on the circuit operation. For example, what happens to the overall circuit operation when a push button is pressed; which relays energize, which lights illuminate, does the pump start or stop, etc. You also need to be able to determine what effect a faulty component may have on the circuit operation.
