Interested in electrical stuff and am trying to learn about it myself (not the greatest idea i know, but its my hobby on the side, may take up a UNI course on it).
So voltage is the electrical force in a circuit, no voltage means no current flowing? Also, how can we create ground in an electrical circuit? I know it is 0V but how do we make 0V on a PCB?,
Given any circuit we assume that the wires have 0 resistance, then if we look at two points in a circuit in which there is no element connected in between them. Then wouldn't the voltage between these two points be 0 and if voltage is 0 then no current flows? Or should i be thinking of it as if the voltage between these two points is 0 then we have a short circuit therefore current flows. (This does not make sense to me as if V = 0, then I = 0 - no voltage to push electrons, no current).
In a short circuit the voltage - 0, then is current as large as you want or 0 (once again its this if no electrical force then no current thing which is causing me headaches). Also for an open circuit, if no current flows then why can we have a large voltage?
Thanks in Advance to everybody!
