USPS 955 Electrical Part Questions with 100%
Correct Answers
current
# of electrons passing a given point in a second
Voltage
The difference in electrical potential energy between two places in a circuit.
Ohm's Law
voltage = current x resistance
Coulomb
A group of flowing electrons
1 amp = 1 coulomb
transformer
A device that increases or decreases the voltage of alternating current by magnetic coupling
Inductor
A coil or wire that creates a magnetic field when current passes through it.
Capacitor
Used to store energy between 2 plates. Used as an ac filter for full wave rectification
Phaser diagram
Uses vectors to show angular difference between different waveforms
