Basic Electrical Theory: Unit 7 - The Electrical Circuit

Electrical pressure is called "_____," and it is measured in Volts.

EMF or potential

Aluminum has a lower resistance to the flow of electrons than does copper.

False

Every component of an electrical circuit contains resistance, except the power supply.

False

"_____" is defined as the rate of work measured by the unit called the watt.

Power

According to the Conventional Current Flow Theory, a positive charge flows from positive to negative in the circuit.

True

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.

True

DC power is determined by multiplying the electromotive force by the circuit intensity.

True

Power is not equal to E x I for ac circuits because consideration must be given to inductive reactance.

True

Smaller conductors have greater resistance and larger conductors have lower resistance.

True

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.

True

In electrical systems, the volume of electrons that move through a conductor is called the "circuit _____."
