Transformer Power Throughput
 

Hi! I got my hands on a couple of toroids, two 2.25" OD and a 2" OD toroid. I was hoping someone could help me out in calculating the power throughputs for each @100kHz. I am not sure about the material though as I bought them from a local junkyard.

Cheers :)

the power output depends mostly on how much winding u can fit in the core .more power -thicker windings

Alot of it also depends on the winding ratio. More secondary then primary equals more voltage which means more amps which equals more watts for a given ohm load.
