V1 has rms voltage of Vrms=10V. The turn ratio of the primary to secondary side of the transformer is 1:10. If R1 has a value of 20Ω, what is the value of the rms current on the secondary side? what is the value of the rms current on the primary side?

Answer 1

I1 = Vi/R1 = 10/20 = 0.5A. = RMS current on primary side.

I2 = I1/10 = 0.5/10 = 0.05A = RMS current on secondary side.
