## Quiz on Electrical Circuits

The sample 15 questions are listed below.

Question 1:

The flow of __________ in an electrical circuit is actually the forced movement of electrons along the length of the circuit conductors by the pressure of the __________ applied.

Question 2:

The power factor of an AC circuit is the ratio of the __________ power to (divided by) the __________ power of the circuit.

Question 3:

__________ overcurrent normally involves an accidental cross-connection of at least two circuit conductors (supply and return).

Question 4:

The power factor of an AC circuit is the ratio of the __________ power to (divided by) the __________ power of the circuit.

Question 5:

The components required for electrical induction to take place in a generator, transformer, or motor, include ____________.

Question 6:

The circuit conductors within an electrical circuit must be __________ to ensure that current is directed or conveyed only to the connected load.

Question 7:

Two forms of current control are normally installed in series with the connected load of an electrical circuit: â€‹

A switch to provide __________ and an overcurrent protection device to provide __________ control.

Question 8:

The power factor (pf) of an AC circuit will always be a value __________ 1.

Question 9:

The rated __________ of given wire size is normally defined as the magnitude of load current the conductor can carry (convey) continuously without overheating.

Question 10:

For a small-scale electrical-power generation, the generation of AC power is normally limited to a __________ AC source.

Question 11:

To protect against the flow of high-magnitude fault overcurrent, the wires along the length of the electrical circuit must be ____________ to provide a single path for the current to flow.

Question 12:

The three major categories or divisions (types) of overcurrent are ____________, _____________, and _____________.

Question 13:

When a switch is placed in series with the supply power, ____________ control has been added to the basic electrical circuit.

Question 14:

The means of ____________ control in an electrical circuit is normally an overcurrent protection device, which at the electrical-power distribution level (the service, the feeder, or the branch circuit) is a fuse or circuit breaker.

Question 15:

In a 3-phase__________ wiring configuration:â€‹

The 3-phase AC line voltage and the individual single-phase winding voltage, measured between any two of the three supply lines in the 3-phase alternator, motor, or transformer, are equal.â€‹

The magnitudes of the 3-phase AC line current are 173% greater than (times 1.732) the single-phase AC winding current.
