Electrical Terms
Concept | Description |
---|---|
Voltage | Usually referred to as "Electromotive Force" (EMF). This force causes electrons to move from negative to positive. |
Current (Amperage) | A unit of measurement referring to the intensity, or amount of electrical force through a circuit. |
Direct Current (DC) | Current that flows only in one direction. DC current is used in applications like low-voltage conditions, circuits conducted over relatively short distances, and appliances with electronic controls. |
Alternating Current (AC) | Electrical current that flows in one direction and then reverses itself and flows in the opposite direction. In 60-cycle current, the direction of flow reverses every 120th second. |
Resistance | The restriction to the flow of electricity in a circuit. Measured in ohms (Ω). Infinite Resistance means so much resistance that current cannot flow through the circuit (“open” circuit). Zero Resistance means no resistance and current can flow through the circuit (“closed” circuit). |
Wattage | The unit of measurement for power, or the work being done by electricity. |
Load | Component that converts electricity to heat, light, or motion. All loads restrict the flow of electricity while performing their work. |
LED | Light Emitting Diode. A low voltage bulb used to illuminate numbers on control panels and other displays. |
Conductor | Material through which electricity can flow. It will usually be a copper wire, and sometimes the chassis, or metal frame, on which the components are mounted. |
Short | A circuit that offers no resistance to the flow of current through it. A direct short will cause a fuse to blow or possibly start an electrical fire. |
Shorted Switch | A switch that offers no resistance to the flow of current through it. The switch may have a shorted contact. |
Open Switch | A switch that will not allow current to flow through it. The switch may have an open contact. |
Shunt | A bypass around a load that still offers resistance in the circuit for the flow of current. |
Closed Circuit | A complete path through which electricity can travel. |
Open Circuit | A circuit in which the path for current has been broken. |
Short Circuit | A circuit in which the current has been diverted from its intended path into a side current of lower resistance. |
Ammeter | A test instrument used to measure current. |
Armature | The section of a motor that turns. |
Air Shutter | An adjustable shutter attached to the primary air openings of a burner used to control the amount of primary air entering the burner. |
Aldehyde | A class of compounds that can be produced from incomplete combustion of gas fuels. |
Allen Wrench | An L-shaped tool that is used to remove hex screws. |
Alternating Current (AC) | Electrical current that flows in one direction and then reverses itself and flows in the opposite direction. In 60-cycle current, the direction of flow reverses every 120th second. |
Ambient Temperature | Temperature of air that surrounds an object on all sides. |
Ampere | The number of electrons passing a given point in one second. |
Bake Element | Lower heating element in an oven used for baking foods. |
Belt | A band of flexible material used to transfer mechanical power from one pulley to another. |
Bimetal (strip or thermostat) | Two dissimilar metals joined together to form one unit with a differential expansion rating. It will bend if there is a temperature change. |
Blower Wheel | A device attached to the indoor side of the fan motor shaft used to circulate air across the evaporator coil. |
Bracket | A hardened structure used to support a component. |

Parts Terms
Concept | Description |
---|---|
Motor | The motor is generally the part that drives a system of a product such as a washer, dryer, refrigerator, or dishwasher. |
Pump | The pump is the part that removes water from an appliance such as a washer or dishwasher. |
Fill Valve | The fill valve allows water to flow into the washer, dryer, refrigerator, or dishwasher. |
Belt | A band of flexible material used to transfer mechanical power from one pulley to another. |
Condenser Motor | A condenser motor cools the condenser coil to remove the heat from the refrigerant. |
Light Switches | Light switches allow the interior light to turn on and off in refrigerators, dryers, and microwaves. |
Evaporator Motor | An evaporator motor is a motor found in the freezer. It moves cold air from the freezer to the refrigerator. |
