Electricity
A form of energy that produces light, heat, and magnetic and chemical changes
What is electricity?
Provides the force to move electrons in the conducting material
What is a source?
Changes direct current (DC) to alternating current (AC)
What is an inverter?
Has constant amplitude over the pulse duration
What is rectangular / pulsewave?
Contains a fine metal wire; allows current to flow through it; cannot be reused
What is a fuse
What is an insulator?
Has a positive terminal and a negative terminal; produces only direct current
What is a battery?
Changes alternating current (AC) to direct current (DC)
Periodic waveform that instantly transitions between two levels of rise and fall times at a steady frequency
What is a square waveform?
Contains two pieces of metal that contact each other. If flow of electricity is too high the two pieces separate and break the circuit.
Circuit breaker
What is a volt? (voltage)
Closed path through which the electrons travel
What is a circuit?
Adjusts flow of current that can change volume or intensity of voltage
What is a rheostat?
Linear wave motion with periodic rise and fall times in a motion that is up-and-down or side-to-side
What is a sinusoidal (smooth wave) waveform?
For fire extinguisher use, remember this
What is PASS?
(Pull the pin
Aim the hose
Squeeze the handle
Spray the chemical)
A unit of electric resistance
What is an OHM?
More than 1 item can be plugged into the same circuit; each item can be run alone or at the same time
What is parallel wiring?
Transfers electricity by an oscillating magnetic field that connects two or more electrical circuits
What is a transformer?
Periodic waveform in which the rise time and fall time are different
What is a saw-toothed wave form?
Installed in areas where electricity and water could come in contact
What is a GFCI?
A unit of electric strength
What is an amp? (ampere)
Most common current used in business and in the home where electrons flow first one direction then in the other
What is an alternating current?
What is a capacitor?
Periodic linear waveform that has rise and fall times that are equal
What is a triangular waveform?
A stationary electric charge, typically produced by friction that causes sparks or crackling or the attraction of dust or hair
What is static electricity?
