Current transformers, how do they work

A current transformer does not have to be different than an ordinary transformer. The theory of operation is described and demonstrated. It is shown how a 50/60 Hz current transformer can be made from an ordinary transformer.

Very interesting!

Thanks for your comment.

Thanks Jim, very cool!
Often wondered if you could have ahalf a turn, use to think it was a bit like digging a halfa hole!
Now I know different.
Seems to be only applicable - half turn part - to the EI core transformers, can't see how it can be done on a toroid.

Hi Mark. I really liked your cover of "walking on the moon" Great production also. Best regards.

@@Jimscoolstuff Thanks Jim, that was my son Jarrod. He is the musical one in the family.
It was a demo of a guitar repair I did for a customer.

Loved the demo using the modified transformer! Would the output voltage still be proportional to the input current if it was rectified and converted to DC?

[@Jimscoolstuff]

I did try that and found the output was not very linear. I don't know why this did not work. If anyone reading this knows the answer please let us know,
