The 8 Ohm Load That Became 128 Ohms
Voltage scales with turns ratio, but impedance does not. An 8 ฮฉ load can appear as 128 ฮฉ through a 4:1 transformer.
Concept: Transformer Reflected Impedance
Voltage scales with turns ratio, but impedance does not. An 8 ฮฉ load can appear as 128 ฮฉ through a 4:1 transformer.
