________ force and ________ attraction.
Centrifugal force & electrical attraction
electromotive force (emf)
Electrons can be moved from one atom to another by
applying some form of _________ or pressure.
Amperage (amps)
The measurement of the amount of electricity flowing past a
given point in a conductor per second (i.e., current).
Voltage
,an electromotive force or potential difference expressed in
volts.
Resistance to the flow of electrons is measured in
_________.
Ohms (Ω)
The difference in voltage between two points is called
_______ potential.
Electrical
Alternating current will produce a ______ wave.

Unit of measurement for frequency (cycles per second). Only
for AC.
To measure the insulation of a rubber-covered electrical
cable, the instrument to use should be....
Ohmmeter
Load
The work required to be done. Observed as an amperage
draw in an electric circuit.
voltage drop
The difference in an electrical potential between two points.
Short circuit
, A connection that allows current to take an unintended path.
True statement
Whenever current flows through resistance, heat is
produced.
What is an ampere?
A measure of current.
Equals one coulomb passing a given point in one second. A
measure of electricity flowing through a circuit.
Ohm's law equation
E= I x R
E= volts or EMF or pressure or potential
I= Amps or current
R= resistance or ohms
Short circuit
A connection that allows current to take the path of least
resistance
