Voltage
 The force that is created pushes toward ______ and away from _______ . 
The force that is created pushes toward <the opposite charge> and away from <the like charge>.


Voltage
 The unit of measurement for voltage is _______, and is defined as the amount of ____, per ____ _____, needed to separate the charges. 
The unit of measurement for voltage is <volt (V)>, and is defined as the amount of <work>, per <unit> <charge>, needed to separate the charges.


Current is represented by the letter "_". The unit of measurement for current is ______, and is defined as the number of _____ per ______ that pass by a point along a path.

Current is represented by the letter "<I>". The unit of measurement for current is <Ampere (Amp)>, and is defined as the number of <charges> per <second> that pass by a point along a path.


Resistance is represented by the letter "_". The unit of measurement for resistance is the ____. The symbol comes from the Greek capital letter ________.

Resistance is represented by the letter "<R>". The unit of measurement for resistance is the <ohm (Ù)>. The symbol comes from the Greek capital letter <"Ù"  omega>.

Electrical pressure due to the separation of electrons and protons.


Impedance is the measure of the combined opposition to the flow of
A. AC and DC current flow. B. Voltage and resistance. C. Ohms D. None of the above 
B. Voltage and resistance.

Voltage
 "Electrical current", or "current", is is caused by a flow of ________. A. Free radicals B. Releasd protons C. Free electrons D. Volts 
C. Free electrons


Ohm's Law relates to the amount of current that will flow through a piece of conductor when a voltage is applied to it. If the resistance of the piece of conductor is R Ohms, then the current that will flow is
A. V = I/E B. I = VR C. I = V/R D. I = R/V 
If the resistance of the piece of conductor is R Ohms, then the current that will flow is I = V/R.
C. I = V/R
