Main Question or Discussion Point
Let's assume a 2:1 transformer which has a 100V Source connected on the primary circuit and has no/negligible resistance, on the secondary circuit a 5 Ohms resistor is connected. Using the 'Impedance Transfer/Reflection' method, the primary circuit would act as if there was a 25 Ohms resistor connected to it, which means a current of 4 Amps would be flowing in the Primary.
My question is how the 5 Ohms resistor from the secondary side 'actually' affects/creates a 'resistance-like effect on the primary side? Aren't they separate circuits? Or does it has to do with the magnetic field that links one another?
A simple concise explanation would be very helpful!
