    High School Proton or Electron: Who's Faster?

    relative masses: mass of a proton = 1 mass of an electron = 1/1840 relative charges: proton= +1 electron= -1 clearly the electron is far much lighter than the proton,so it will be moving faster.

    Undergrad The Generation of Voltage in a Transformer

    power(watt) = voltage(V) x current(A) (P=VI) the power input = power output in a transformer so V and I change themselves keeping the power P constant & since Energy = Power x time Energy is conserved

    Undergrad The Generation of Voltage in a Transformer

    yep the voltage is increased or decreased, depending on the number turns in the secondary coil. but Power remains constant ... so energy conserved...
