Does current decrease as it passes through resistor?

  • In electrical circuits, since resistors obstruct flow of charges, shouldn't electric current decease as it passes through the resistor? It doesn't, but why? In this video, let's clarify this misconception once and for all. We will start by exploring what's wrong with our model and then go on to correct it. By the end of the video, you will have a better sense of electrical circuits?

      @@harshad1526 once battery is connected it develops potential diff. B/w the two points. Due to this electric field is created in a certain direction (from higher to lower potential). And we know the free electrons are present everywhere in the wire. So they will go in a particular direction i.e. opposite of the electric field.
      There is no first electron.the electrons are everywhere in the wire (from start of the wire to the end of wire )
      Just u connect a battery they all will go in a particular direction.

      It isn't really. You have just two parallel roads one is faster, one is slower. Ok at the junctions the analogy falls apart a bit but if you ignore the j junctions or consider the junction the starting point, it equalizes. Kinda. Sorta. Guess you need to remember a resistance has global influence on both sides. But yeah the analogy gets fuzzy, since the simplified resistance if you calculate it for a parallel circuit is
