Basic Elec Flashcards
Electricity
A fundamental property of matter, associated with atomic particles whose movements develop fields of force and generate kinetic and potential energy
Voltage, Volts, V
It is the pressure or force that drives the electrical charge
Call out bubble
Used for tracing a circuit that continues onto a different sheet. The square applies to the light circuit
Test point
Point accessible on a component to take measurements with BOB/Multimeter. Test points are contained within test jacks
Silicon controlled rectifier
A semiconductor that’s basic purpose is to function as a switch that can turn on and off and control large amounts of power.
Transistor
A three electrode semiconductor used as either a switch or an amplifier.
Solenoid
An electromagnet coiled around a movable plunger (armature) when the current energizes the electromagnet the plunger will move to the strongest magnetic field which is the center of the coil
Switch
Device used to open/close the current path of one or more circuits
Momentary switch
When pressed closes a circuit
Resistor
A device capable of providing resistance in an electrical circuit. Used to set up a specific circuit condition by controlling current flow or setting up voltage at a point within a circuit.
Wire
A wire moves electrical current and signals from one point to another point.
Wiring harness
A grouping of several wires together in a bundle. A wiring harness may only have two connectors or branch into several.
Wire connection
Common point where two wires joined
Relay contact
Controlled by a relay coil. Contacts can either be normally open or normally closed
Relay coil
Device using an electromagnet to control a single relay contact or sets of relay contacts. When current flows through the relay coil it is energized which changes the contacts to the opposite of their original position
