current flow.
ground - Correct answer-A(n) ____ circuit is a conducting connection between
electrical equipment and the earth.
evaporator - Correct answer-A(n) ____ is a heat exchanger through which heat is
transferred to the low-pressure refrigerant liquid.
thermostat - Correct answer-A(n) ____ is a temperature sensor inside a
temperature-controlled space that sends signals to a control system in order to
maintain a set temperature.
