Solved Step by Step With Explanation- Calculate RMS Value

1.Answer

• Vmax​ is the maximum value of the emf (peak value).

In your case, you are given that the maximum value of the flux (Vmax​) is 0.2 Wb, and the transformer has 55 turns in the secondary coil. The supply frequency is 50 Hz.

• N is the number of turns of the coil.

• dΦ/dt​​ is the rate of change of magnetic flux.

T=1/f​

=1/50 Hz

Now that you have Emax​ and N, you can calculate the maximum induced emf (Emax​):

Emax​=−N dΦ/dt

Vrms​=Vmax​​/$\sqrt{}2$

Vrms​=500​​/$\sqrt{}2$
