HVAC electric Test with Complete Solutions Relay - Answer-an electrical device, typically incorporating an electromagnet, that is activated by a current or signal in one circuit to open or close another circuit. ampere - Answer-a unit of electric current equal to a flow of one coulomb per second. Resistance - Answer-the opposition to the flow of electrons Rotor - Answer-the rotaring part of an electrical motor ohm - Answer-the SI unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt. Electricity - Answer-energy that is capable of producing an electron flow Current - Answer-electrons flowing in an electric circuit, measured in amperes. Conductor - Answer-a wire that is used for the path of electric flow A/C - Answer-an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies. Transformer - Answer-a device that decreases or increases the incoming voltage to the desired voltage Volt - Answer-the amount of electric pressure required to force 1 ampere through a resistance of 1 ohm
