Because of the battery polarity it's seen as a -60 volts.

Then you use I=V/R. You know you're looking for the resistor at 10 amps

you have to add the batteries 25 ohm resistance.

The equation becomes IR=V because you're trying to solve for R.

.25ohms * 10 AMPs = 25V which you can subtract from the voltage.

R=V/I so divide 209.2V/10A

The Max AC voltage would be sqrt(2)* V_rms and that we need that value due to the diodes for the full-wave rectifier?
