#1 Interstage question.

Post by pre65 »

If you pass 5.5ma through the 15K primary of an interstage (5-1 ratio) what current will you get on the 600R secondary ?

Is it 5x current and -5x volts ? :?

Yes voltage and current are reflected linearly. Impedance is reflected squared / square routed.

I made it 5 as well. :thumbleft:

Current x5
Voltage /5

In reverse, sec load impedance x25

If its DC then 0ma
