Hi.
I'd like to talk again about a CT (current transformer).
I connect a burden resistor (Rb) to the output of a CT.
The secondary coil has a DC resistance (Rs).
I pass a primary current (Ip) through the CT's core.
I measure the voltage (Vo) across the burden resistor.
From these data - Rb, Rs, Ip, Vo - I'd like to derive N (number of secondary turns) and Is (the current flowing through the secondary coil).
How do I do that?
Thank you.

I'm not sure whether Is equals Vo / Req or Vo / Rb.
Where Req = Rb || Rs
