    Voltage is the energy used to push each coulomb. Current is the speed of each coulomb. Resistance is what slows the current created by the voltage.

    I love your videos. Just the right length to be useful in all sorts of ways. However, I have one slight gripe with this (and possibly other, but I haven't watched them yet) one on electric circuits - you've left gaps between the wires and the components! I know there may be animation reasons for this, but if my students do this in their GCSE they will lose marks!

    • @ballztoeclippings1619
      @ballztoeclippings1619 4 роки тому +3

      The potential difference (or voltage) of a supply is a measure of the energy given to the charge carriers in a circuit. Units = volts (V). This is the voltage between two points that makes an electric current flow between them.

    • @Random-nq4xj
      @Random-nq4xj 4 роки тому +3

      @@ballztoeclippings1619 If 9V means that 9 joules of energy is transferred by every coulomb of charge, then if all of this energy carried by the electrical current is transferred into light/thermal energy in the lamp, then how does the electrons have any energy or "pushing force" left to return to the opposite side of the cell?
      Any help is appreciated!
