Exam 13: Resistive-Inductive Series Circuits

A _________________________ is a four-sided form whose opposite sides form parallel lines and whose angles are not required to be 90 degrees.

If an industrial plant consumes 5 MW of power per hour with a power factor of 60%, the power company must actually provide 8.33 MVA per hour. If the power factor were to increase to 95%, the power company would have to provide ____________________ MVA per hour to provide the same amount of power to the plant.

A decimal value can be changed to a percent value by multiplying it by ____________________.

VARs is an abbreviation for ______________________________.

The ____ of angle theta is the power factor.

Since true power, or watts, can be produced only when the ____ are both positive or both negative, only resistive parts of the circuit can produce watts.

Volt-amperes is the ____________________ power of a resistive-inductive series circuit.

When a circuit containing both resistance and inductance is connected to an alternating current circuit, the voltage and current will be out of phase with each other between ____ degrees.

Because resistive-inductive circuits have periods in which voltage and current have opposite signs and where power is returned to the circuit, VARs is often referred to as ____ power.

In resistive-inductive circuits, ____________________ cannot be found by multiplying the total voltage by the current flow through a resistor.

VARs is the amount of ____ power in a resistive-inductive circuit.

Impedance is symbolized by the letter ____________________.

One of the primary laws of series circuits is that the ____ must be the same in any part of the circuit.

Because inductive reactance is an inductive quantity and impedance is a circuit total quantity, Ohm's law cannot be used to find resistive quantities. ______________________________, however, can be used.

The ____ power of a resistive-inductive series circuit can be found when a voltmeter and ammeter are used to measure the circuit voltage and current and then these measured values are multiplied together.

While electric power is sold on the basis of watts consumed, the power company must supply the ____ power.

In a resistive-inductive circuit, the total ____________________ flow through the circuit can be computed by dividing the total applied voltage by the total current-limiting factor.

In an R-L series circuit, the current is the same through both the resistor and the ____________________.

When a pure ____________________ load is connected to an alternating current circuit, the voltage and current are in phase with each other.

Impedance is measured in ____________________.
