    Thank you for providing this fantastic opportunity to all and sundry, we greatly appreciate it. However, I do have a couple of basic queries :

    1) In the book , you mention conventional flow verus actual electron flow -- one of the hardest things that we beginners have trouble understanding is the layout of components in electrical diagrammes, ie
    on your page 94, if the flow of electrons is from negative to positive, why aren't the disconnect switch and the on/off switch between the negative side of the battery and the load ?

    2) The other thing that is difficult to understand is the use of the 'earth'. You don't actually say how this works...ie on p94 diagramme 1, why isn't the voltage / current split between the earth wire and the wire to the load ?


    Thank you
