  • 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.

    That outro... omg XD. I wish a lot more teachers were this fun, it would be harder to NOT pay attention to them.

      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.

      @aravindansundaram4010 5 лет назад +2

      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..

    I've watched many transformer vids, but this is the first one I found that answers that question... "who's buying?". Thank you (8 years later).

    I'm taking courses in electronics and sought out some RUclips videos to break the monotony of reading. I greatly appreciate how you explain how Faraday's Law works with the transformers ... that was in my text but trying to read it just makes my head hurt. Your way of explaining helps a lot. Thanks!

  • @DocSchuster
    @DocSchuster  11 лет назад +3

    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.

    I love your electricity math and circuit videos, they are the best on the net.
    One thing to point out is, the power to feed homes in north america is 240v not 120v as most people think. It's a 3 wire system giving the option of 240v and 120v service to homes.

    • @DocSchuster

    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.
