Question

A ideal transformer shown in the figure below having a primary with 25 turns and secondary with 15 turns.

The load resistor is 67 ?. The source voltage is 80 Vrms.

What is the rms electric potential across the 67 ? load resistor? Answer in units of Vrms.

A ideal transformer shown in the figure below having a primary with 25 turns and secondary with 15 turns. The load resistor is 67 ?. The source voltage is 80 Vrms. What is the rms electric potential across the 67 ? load resistor? Answer in units of Vrms.

Explanation / Answer

The number of turns in primary coil is Np=25

The number of turns in secondary coil is Ns=15

The source voltage is Vp = 80 VRMS

The load is R = 67 ohm

The potential diference across the load is

Vs=VpNs/Np

Vs= 48 VRMS
