Amp restriction mechanism frequency doubling

Now i need to explain how a transformer work

In a transformer the backemf of the primary that restricts the current is the same emf in the secondary, and so as a load is connected to the secondary, the current flow generates an electro magnetic field that kills the primary back emf making a current flow in to the load and primary.   

emf is electromotive force, i coud call it voltage , or talk about effective voltage across the inductor being the applied subtracted off the Back voltage to the source or back electromotive force.

The amp restriction is this extreme abruptness where electrical stress is propagated while no current is flowing.

I think he talked about the isolated ground to highlight the use of high potentials relative to ground as to confirm his ability to apply high electrical stress on the discontinuity consisting of the cell.

Are we are talking about a Resonant transformer SRF and not an 'standard' type?

Here the primary is pulsed and has a diode and resistor parallel to the coil, so EMF is blocked and dissipated.


Not answered my question: why are the blue and yellow scope traces not opposite but equal in amplitude?

whatever transformer...

about your question, i didn't understood... or i need more info to answer...

If you connect gnd between sec B- and negative choke you have zero volts at the negative choke B- !

Stan said primary coil is isolated from the secondary coil. Only mutual inductance.

Why is the negative choke tuned? ... To adjust the opposite but equal voltages, right?

I meant the back emf at the primary is only EM coupled to the emf at the secondary... they are all one and same thing. so if you load the emf at the secondary you reduce the bemf at the primary raising the effective voltage raising there to the amp flow...

I'm posting this info because is the way we can get to understand why it is tuned... =)

Now i'm going to think about the interaction of a choke on the amp restriction mechanism of the transformer...

The question of the day would be why it subtracts from the other instead of summing...

Just forgot to make it clear, stan says it doubles the frequency again because for each cycle there are two increases and two decreases in magnetic field, so double frequency.
