    Closed: What is electrons number in...

    Hello,
    In 1amp there are 6.25x10^18 electrons and 1v also
    if there is 5V and 2 Amps how many electrons will flow in 1sec?

    how we get silicon wafer who invented that silicon is good for designing's electronics?
    from where silicon is collected for chip
    i have seen people use silicon for panel avoiding rain water.
