Question

You will set up the voltage of your outlet at home (Vrms=120v or Vpeak=170 v) using the above set up with the 200 and 800 loop coils. Which coil will you use as the primary coil? What peak voltage will you get on the secondary coil in the ideal case and in the real case? What voltages would you get in the ideal and real cases if you switched the primary and secondary coils?

Answer 1

At home, we need voltage of the order of 100-200Volt, so we use generally a step down transformer at home in which primary coil should have more turns as compared with secondary coil, so clearly, we will use 800 turns coil as a primary coil and 200 turns coil as a secondary coil.

Peak voltage obtained in ideal case is 170 V as in ideal case we assume that input power = output power, but in real case the output power will be somewhat less due to numerous unavoidable losses, so peak voltage will be less.
