Alternating Voltage is a voltage that:

1- Continuously varies in magnitude 2- Periodically reverses in polarity

The sinusoidal waveform (sine wave) is

the fundamental alternating current (ac) and alternating voltage waveform.

Sinusoidal voltages are produced by

ac generators and electronic oscillators.

sinusoidal wave is generated when

a conductor rotates in a constant magnetic field

When the loop is moving perpendicular to the lines of flux ........... is induced

the maximum voltage

Sine waves are characterized by

the amplitude and period.

The amplitude is

the maximum value of a voltage or current

The period is

the time interval for one complete cycle.

Frequency ( f ) is

the number of cycles that a sine wave completes in one second.

Frequency is measured in

hertz (Hz).

The period and frequency are ....................... of each other.

reciprocals

f=

1/T

when the conductor is moving parallel to the lines of flux....

No voltage is induced

This is the symbol for

sinusoidal voltage source
