Quiz 5

Current and voltage in an AC resistive circuit are ? phase.

in

As frequency increases, skin effect ? .

increase

Factors such as skin effect and eddy currents are present in an AC circuit and, in practice, ? the resistance of the conductor.

increase

Current passing through a resistance produces ? .

a dissipation of power, a voltage drop, and heat

Skin effect and eddy currents ? present in a DC circuit, and, therefore, will not be factors that affect the opposition to current flow in a DC circuit.

are not

The ? value is the actual average of all the instantaneous voltage or current values across a full cycle.

average

In an AC circuit, ? will oppose current flow.

eddy currents, resistance, and skin effect

The ? value of AC voltage will produce the same amount of power as a like value of DC voltage.

effective

The average value of halfwave rectified DC is ? times the peak AC value or one-half of the average value.

0.318

When an AC voltage is given, it is always the ? value unless stated otherwise.

RMS

Skin effect can be ? by using stranded conductors, which provide greater surface area for current than solid conductors.

reduced

In a DC circuit, ? will oppose current flow.

resistance
