Step up, step down, step all around town. But who's buying? This video explains how transformers work. This video introduces some ideas that are pretty tricky. For more detail, check out the videos on Power Distribution. Thanks.

Uh... but power is also equal to V*V/R. (Ohm’s Law). There is a good reason for having high voltage for long distance power distribution but I am not sure you have pointed out the correct reason. I did however, really enjoy your presentation.
@aravindansundaram40106 жыл бұрын
But you only use V2/R when there is uniform voltage throughout... I reckon the voltage between two transmitters are the same but the voltage between the power source and first transmitter is less than the voltage between power source and second transmitter.. So you use V2/R when voltage is same throughout as in a parallel connection in domestic circuits..

Excellent question, dude! It's critical to note that when you use that equation for power lost in the line, V is the voltage DROP across the line. This is VERY often misunderstood. When you talk about a high-V line, you are referring to large V between the line and ground, but saying nothing about the voltage between one end and the other (hopefully the latter is small). You find V across the line by V = IR, so it is more direct to use P = I*I/R to find power loss on the line.

YES! The iron in the core is laminated sheets to prevent eddy currents, which would significantly heat the iron and lower transformer efficiency. You can also make cores out of nonconductive iron-ceramic suspensions for the same reason.
@DocSchuster11 жыл бұрын
A nice sound bite, but it masks some important physics: Sure, current is what harms tissue, but a higher voltage power line (which is not current-limited) will ALWAYS cause a higher current through your fleshy body (that has a fixed resistance) 'cuz V = IR. You need to be WAY more careful around high-voltage lines than low-V lines. It's the current through YOU that matters, and that's determined by YOUR resistance and the voltage across you (from the line to ground, typically). DANGER!

Oh, I understand your confusion. If I just hook up a battery to the primary coil of a transformer, that coil will experience a change in flux, right? The only problem is that the flux will approach a constant (saturated) value based on the steady-state current from the battery. That's why I mentioned a battery.

@DocSchuster11 жыл бұрын
Boy, I'm sure not an expert here, but I'll shoot from the hip. Maintaining safety raises costs while lower current lowers costs. You've also got to have step-up and step-down transformers at each end. So there's a sweet spot that depends on length of run and power needed. Hiring an engineer to find that sweet spot is probably a good idea. Maybe someone who knows more firsthand about power distribution will comment...

I agree with you that cost and safety are factors, but you're confused about the voltage/current danger. Sure, current is what harms tissue, but a higher voltage power line (which is not current-limited) will ALWAYS cause a higher current through your fleshy body (that has a fixed resistance). You need to be WAY more careful around high-voltage lines than low-V lines. Again, that is exactly why they must be higher up and better protected from accidental bumping.

Not quite. Reread the previous post carefully, then continue: The current THROUGH the high-V line will be less than a low-V line that transfers the same power (because power transferred is IV). YOU DON'T CARE ABOUT THE CURRENT THROUGH THE LINE WHEN DECIDING WHETHER TO DIE OR NOT. The current through you is determined by I = V/R, where V is voltage between line and you (assuming you grabbed the dang wire) and R is YOUR resistance. However, Van De Graaffs are another story...

Residential voltage is usually 120/240V. 120V line to neutral and 240V line to line, but I digress, you did an excellent job of explaining, and you kept it interesting.
