How to wire a transformer as an autotransformer - UTSOURCE 

Great video!, but please be careful with this modification the transformer is then no longer potentially isolated! In case of plugging it to mains voltage then you could risk to touch the mains high voltage phase!

very nice explanation! Best regards

very good explanation of wiring up! thanks for sharing

So if the voltage are added and is higher than the input voltage then the current must decline too….. am I right ? Vice-versa…

👍👍👍👍👍👍

Thanks to your video i come back to electronics as a my hobby, thank you 😊
