If I had a step down transformer of 300 VA in size at 45-0-45 Volts@3.3 Amps with a regulation of 10% could I do the following to calculate the internal resistance of the secondary winding for my power supply circuit?
Voltage * Regulation 10% to work out the voltage difference between noload and full load.
45 Volts* .1 = 4.5 volts
Secondary series resistance per winding
4.5 Volts/3.3 amps = 1.36 ohms
I know there is inductance as well but at the moment I am ignoring it.
I need to put values into circuit maker student edition to reflect the real world.
