People say that the voltage across one resistor is equal to the voltage supplied. I've drawn a picture of a simple circuit with two points near the positive terminal. Apparently, if we take the potential difference of these two points, it will equal 9V according to the above saying (which can be found all over google). But then if the potential difference between the two red dots is 9 V, there will be no force driving the current to the negative terminal of the battery. So this one resistor essentially absorbs all of the energy supplied by our battery. I am confused about this.
