ESOT EVAL Exam UPDATED
QUESTIONS AND CORRECT ANSWERS
Ion - CORRECT ANSWER an atom or molecule with a net electric charge due to the loss or
gain of one or more electrons.
Free electron - CORRECT ANSWER Name given to an electron in the outermost orbit that is
easily moved from its orbit
Best conductors in order - CORRECT ANSWER silver, copper, gold, aluminum
What produces current - CORRECT ANSWER the electrical potential between charges, voltage
electrostatic force - CORRECT ANSWER The force between electrically charged objects (like
charges repel and opposite charges attract each other).
Static electricity - CORRECT ANSWER Two items with diff potential come close but don't
make contact. What kind of electricity?
speed of electrical current - CORRECT ANSWER Speed of light or 186,000 miles per second
One amp(ere)—how many electrons and at what rate? - CORRECT ANSWER 6.25 x 10^18
electrons flowing past a given point per second
Giga - CORRECT ANSWER 10^9 (1,000,000,000)
Mega (M) - CORRECT ANSWER 10^6 (1,000,000)
kilo (k) - CORRECT ANSWER 10^3 (1000)
milli (m) - CORRECT ANSWER 10^-3 (0.001)
, micro (u thing) - CORRECT ANSWER 10^-6 (0.000001)
Joule's Law - CORRECT ANSWER H = W = I^2Rt (h= heat)(t=time)(heat in "joules")
Joule's first law - CORRECT ANSWER 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 - CORRECT ANSWER 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? - CORRECT ANSWER Voltage and resistance
What is additive in a parallel circuit - CORRECT ANSWER Current
What stays the same in a series circuit - CORRECT ANSWER Current
What stays the same in a parallel circuit? - CORRECT ANSWER Voltage
Total resistance, equal resistance loads, equation - CORRECT ANSWER R/n
Total resistance in parallel - CORRECT ANSWER 1/Rt = 1/R1 + 1/R2 + 1/R3
Product over sum formula when? - CORRECT ANSWER 2 resistors of equal value
2 resistors if equal value formula aka and what is it - CORRECT ANSWER Product over the
sun formula,
R_T= (R1 x R2)/(R1 + R2)
