Question

a waveform having form factor 1.2 and peak factor of 1.5 to the maximum value 100v its rms value and average value are​

Answer 1

Answer:

Given:

Form factor = 1.2

Peak Factor = 1.5

I_{max} = 100 AI

max

=100A

To Find:

R.M.S value and average value of current.

Solution:

We know that peak factor of a wave is given by

Peak factor = \frac{I_{max}}{I_{r.m.s}}=

I

r.m.s

I

max

1.5 = \frac{100}{I_{r.m.s}}1.5=

I

r.m.s

100

I_{r.m.s} = 66.6AI

r.m.s

=66.6A

Form factor = \frac{I_{rms}}{I_{av}}=

I

av

I

rms

1.2 = \frac{I_{66.6}}{I_{av}}1.2=

I

av

I

66.6

I_{av} = 55.5AI

av

=55.5A

Thus, Average value of current is 55.5A55.5A and r.m.s value of current is 66.6A.66.6A.

Thus, Average value of current is 55.5A55.5A and r.m.s value of current is 66.6A.66.6A.
