Asked by student

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?
Answered by Henry
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.
