  • if electrons move at the speed of light, how can current be the speed of the electron?

  • @skythani Electrons don't move at the speed of light. The EFFECT of the movement is felt at the speed of light. Some people like the "ping pong balls in a tube" example, though it's not my favorite. If an electron move at one end of a 186,000 mile wire (ignore resistance) then the electron at the other end will move one second later. The first electron hasn't actually traveled 186K miles...

  • Where do those electrons from battery dissappear, because if you measure voltage of a new 9v battery you get 9-10v , and with an old you get less?

  • @kaulassala Well, it's not that they disappear, really. They're still there, but the chemical reaction gets weaker, so the battery isn't producing as many. It is a weird thought, and it is a little hard to understand (I still have to think about it...). What happens is that the energy that the electrons originally have is used up to make the light, or the heat, or the magnetism, so their pressure drops. A weak battery just has less energy because fewer electrons are father apart - less voltage.

  • where do watts fit in or do they?

  • @dialectical44 WATTAGE (W) is a measure of Power, and is the same as HP. In electricity, the power of a circuit is determined by how many volts (pressure) are pushing how many amps (flow). Same idea as shop air. Full pressure (120 psi) with a 3/4" hose has more power than 90 psi and a 1/2" hose. In Ohm's Law, A & V are on *opposite* sides of the equation, In the Wattage formula they're on the *same* side. Ohm's Law is V÷Ω=A, and Wattage is W=AxV ("wave"). Remember though, Ohm's Law is a concept.

  • so Volts are the Electrons moving and The Amps are the speed or frequency in which they move.

  • does resistors use up energy "voltage" or drop voltage a bit to slow down currents?

  • Excellent presentation,Liked and subscribed..Cleared up a lot of fuzzy and blank areas for me.

    With your obviously better understanding of electronics,could you tell me if you believe that the US patented 15hp magnetic driven motor of Howard Johnston in 1979 was real.

    I would like to build a smaller version for test purposes,and would appreciate your point of view on the possibilities of a magnetic driven motor.I am aware of The law of Conversion,but maybe there are other unseen factors.

  • Thanks mate made thing a lot clearer you should put more videos up!:)

  • I just make this account to tell your tut rule !

  • there should be no "dislikes"---he explained this better than any professor i've ever had!

  • Studying perioperative nursing (electric diathermia and so on). 10+ years since i touched a book on this subject. Your movie got it all back in less then ten mins. Thanks!

  • great tutorial
