Part E

What is the frequency of the source?

Express your answer in hertz to three significant figures.

Part F

What is the angular frequency of the source?

Express your answer in radians per second to three significant figures.

Explanation / Answer

A..

in the graph , we can see that the max voltage is

Vmax = 3.0 V

B.

the average voltage of the source is

Vavg = (1/T) V * sin t *dt

= 0
here the Integral over entire cycle for sin t is zero.

C.

the root-mean-square voltage of the source is

Vrms = Vmax/ 2

= 3 /2

= 2.12 V
D.

period of the source = Time from one maxima to next maxima

T = 0.08 s

E.

the frequency is

f = 1/T = 1/0.08 = 12.5 Hz
F.

Angular frequency is

= 2* f

= 2 * 3.14 *12.5

= 78.54 rad/s
