Basic Electrical Theory: Unit 7 - The Electrical
Circuit Questions & Answers 100% Correct!!
According to the Electron Current Flow Theory, electrons flow away from the negative terminal of
the source, through the circuit load, toward the positive terminal of the source. - ANSWERTrue
"_____" is defined as the rate of work measured by the unit called the watt. - ANSWERPower
According to the Conventional Current Flow Theory, a positive charge flows from positive to negative
in the circuit. - ANSWERTrue
Power is not equal to E x I for ac circuits because consideration must be given to inductive reactance.
- ANSWERTrue
Electrical pressure is called "_____," and it is measured in Volts. - ANSWEREMF or potential
The work that can be performed by the moving electrons dependents on the circuit pressure and the
circuit's opposition to the flow of electrons. - ANSWERTrue
Every component of an electrical circuit contains resistance, except the power supply. - ANSWERFalse
DC power is determined by multiplying the electromotive force by the circuit intensity. -
ANSWERTrue
Smaller conductors have greater resistance and larger conductors have lower resistance. -
ANSWERTrue
Aluminum has a lower resistance to the flow of electrons than does copper. - ANSWERFalse
In electrical systems, the volume of electrons that move through a conductor is called the "circuit
_____." - ANSWERintensity
