Question

a certain wave form has a form factor of 1.2 and a peak factor of 1.5. if the maximum value is 100 , find the r.m.s value and average value.​

Answer 1

Given:

• Form factor  = 1.2
• Peak Factor = 1.5

• $I_{max} = 100 A$    

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  $= \frac{I_{max}}{I_{r.m.s}}$

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

                          $I_{r.m.s} = 66.6A$

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

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

               $I_{av} = 55.5A$

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