Connecting two HF transformers together. What will happen?

[neazoi]

Hello I have two HF toroid transformers with some windings. Consider only windings A, C and A2, C2 in the picture attached, ignore all the others.
C is 1 turn and A2 is say 10 turns.

What will be the result of connecting them this way?

For example a signal of 1v (pp) that comes out of the C how is it affected by the A2 winding and what would be the result at C2?

Or in reverse, a signal of 1v (pp) that comes into C from A2, how is it affected by the C winding and what would be the result at A?

If a third transformer was connected between C and A2, it is obvious what the resulting voltages be, but without this transformer what is the result?

Hi as assuming the Ideal transformers if the turns ratio (Ns/Np) is more than 1 then it is a step up transformer (a voltage step up trans former reduces the current by the same ratio), if it is less than 1 then it is a step down transformer..

now cascading the transformers increases the same effect..
for example if you give 10Vpp at coil A, It will be 1 V at coil C (turns reduces) That is fed in A2 so C2 will have .1V and go on..
In reverse if you give 1Vpp in C2 It will be 10Vpp in A2 and 100Vpp in A (assuming coil resistance 0 and source internal resistance 0 and core non saturated)...
It may not happen with ur 10 to 1 ratios but will surely done in higher ratios.......
