Free electron - Answers Name given to an electron in the outermost orbit that is easily moved from its
orbit
Best conductors in order - Answers silver, copper, gold, aluminum
What produces current - Answers the electrical potential between charges, voltage
electrostatic force - Answers The force between electrically charged objects (like charges repel and
opposite charges attract each other).
Static electricity - Answers Two items with diff potential come close but don't make contact. What
kind of electricity?
speed of electrical current - Answers Speed of light or 186,000 miles per second

a given point per second
Giga - Answers 10^9 (1,000,000,000)
Mega (M) - Answers 10^6 (1,000,000)
kilo (k) - Answers 10^3 (1000)
milli (m) - Answers 10^-3 (0.001)
micro (u thing) - Answers 10^-6 (0.000001)
Joule's Law - Answers H = W = I^2Rt (h= heat)(t=time)(heat in "joules")
Joule's first law - Answers The total amount of heat developed in a conductor is directly proportional
to the circuits resistance, the square of the current flowing in the circuit, and to the length of time
during which the current flows
electrical power - Answers the rate at which electrical energy is converted to another form of energy
P=w/t= i^2 x r
What is additive in a series circuit? - Answers Voltage and resistance
What is additive in a parallel circuit - Answers Current
What stays the same in a series circuit - Answers Current
What stays the same in a parallel circuit? - Answers Voltage
Total resistance, equal resistance loads, equation - Answers R / n
Total resistance in parallel - Answers 1/Rt = 1/R1 + 1/R2 + 1/R3
Product over sum formula when? - Answers 2 resistors of equal value
2 resistors if equal value formula aka and what is it - Answers Product over the sun formula,
R_T= (R1 x R2)/(R1 + R2)
Transmission voltage range - Answers 69kv - 500kv
Generators produce at what voltage, and what is most common - Answers 18kv most common, 4160,
11kv and 24kv
Early transmission lines what voltage - Answers 10kv-20kv
Extra high voltage is - Answers 500kv and up
Transmission voltages/ most common? - Answers 115, 138, 230, 287, 345, 500 (230 and 138) ALL KV
Technically 69kv is LADWP trans and sub trans for other utilities

Sub trans voltage range - Answers 7.5kv-69kv
Peddler - Answers Sub trans circuit emanating from RS, DS or 34.5 IS and terminating at IS and/or pole
top switches
Ending with a number = overhead
Letter= underground
