CM 411 Quiz 1 With Highest Ratings
Newest Update 2024/2025 !!
Current - CORRECT ANSWER-A flow of electric charge.



Amperes - CORRECT ANSWER-the unit for measuring electrical current; the
abbreviation is amp.



Conductor - CORRECT ANSWER-A material that allows heat and electricity to pass
through it.



Insulator - CORRECT ANSWER-A material that does not allow heat or electrons to
move through it easily.



Electromotive Force (EMF) - CORRECT ANSWER-The power supplied by the supply
per unit current.



Potential Difference - CORRECT ANSWER-the difference in electrical charge between
two points in a circuit expressed in volts; compare two different points; more electrons at
one point than the other



Voltage - CORRECT ANSWER-an electromotive force or potential difference expressed
in volts.



Resistance - CORRECT ANSWER-A material's opposition to the flow of electric current.



Ohms - CORRECT ANSWER-unit for resistance



Ohms Law - CORRECT ANSWER-the current in a circuit equals the voltage difference
divided by the resistance; Voltage = Current x Resistance

, What are the three fundamental concepts of electricity - CORRECT ANSWER-Current
(Amps)

Electromotive Force (Volts)

Resistance (Ohms)



How do volts relate to amps and current and ohms and resistance? - CORRECT
ANSWER-One volt of potential difference is required to force one amp of current
through one ohm of resistance



What are the three requirements of an electrical circuit? - CORRECT ANSWER-1)
Conductors

2) Source of EMF

3) Load (device that uses electricity)



Parallel Loads - CORRECT ANSWER-most commonly used in construction because
voltage is constant throughout the whole building; (1) there are multiple paths for the
current to follow (currents add) (2) Voltage is constant



Series Load - CORRECT ANSWER-a series of loads connected; (1) only one path for
the current to follow (2) Voltages Add



What happens when current passes through a load? - CORRECT ANSWER-There is a
loss in pressure; the voltage drops



Units of Energy - CORRECT ANSWER-Energy = Kilowatt x hours



Units of Power - CORRECT ANSWER-Power = Watts = Volts x Amps



What does MW capacity tell us? - CORRECT ANSWER-how much energy the power
plant is capable of producing every hour



Heat from Electricity - CORRECT ANSWER-Heat produced by current = I^2 x R
