To think that in order for me to watch this video, various transformers had to do exactly this kind of things is just wild

[tedlahm]

Higher voltage equates to more Watts on/from the same size conductor.

I took your previous course. Thank you.

The Transformers: More Than Meets the Eye

[Teh_Random_Canadian]

Very good and concise video. 👍 As an electrician I will be sending new apprentices to this video and your channel in general.

[Burnt_Gerbil]

For transforming one voltage into another. Either up or down.

[tmhchacham]

Very nice explanation. These basics are amazing!

[clusterstorm]

In my country the philippines, , the voltages sometimes 230-250v ac...

What's the difference between a Step up Transformer and a step down transformer? Does it just matter on how you hook up to it? Like if I hook it up in this direction it steps up, but if I hook it up in this direction it steps down.

[MarekKnapek]

Not sure everybody gets the point. Because P=I^2*R then by increasing voltage 10× you decrease current 10× and decrease losses 100×. Now, instead of 10× and 100× we are using something like 1000× and respectively in case of 400kV and 0.4kV (380V three phase in Europe).

Next please put the ac to dc rectifier in center taped transformer and non center taped transformer

[sandis]

Hey, why is Power loss = Current ^2 x Resistance ?

[LYSYRGIX]

So wait. In theory, with thin enough wire in an inert gas, couldn't you amplify a TINY voltage into a HUGE one? Genuinely curious if that would even chamge anything or what would happen

[MandrewP]

A transformer to electrical is the exact same as a transmission to mechanical. It changes the voltage / current - rpm / torque ratio.

The power consumed is also equal to v²/R. In that case for 40, 000volt the energy dissipiated would be higher than that at 230v. Isnt it?? Please make me clear on this.

[naranathubhranthan]

Why didn't current increases with increase in voltage 🤔

[ftscotttinez]

Could you relate this to three phase voltage sources and loads?

[OrdinaryDude]

AC transformers are what ultimately led to the defeat of Edison’s DC system.
