1

Alternating Voltage is a voltage that:

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

2

The sinusoidal waveform (sine wave) is

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

3

Sinusoidal voltages are produced by

ac generators and electronic oscillators.

4

sinusoidal wave is generated when

a conductor rotates in a constant magnetic field

5

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

the maximum voltage

6

Sine waves are characterized by

the amplitude and period.

7

The amplitude is

the maximum value of a voltage or current

8

The period is

the time interval for one complete cycle.

9

Frequency ( f ) is

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

10

Frequency is measured in

hertz (Hz).

11

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

reciprocals

12

f=

1/T

13

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

No voltage is induced
