Output Transformer Impedance

https://www.radioremembered.org/outimp.htm

Again using ohms law, the impedance of the primary is now 500 ohms. Z = E/I Z = 100/.2 = 500 ohms This is called the reflected load. A 10 ohm load reflects back a 1,000 ohm impedance, while a 5 ohm load reflects back a 500 ohm impedance. The reflected impedance is a function of the turns ratio of the transformer.
