drop of voltage in resistor has confused me. I know base on V=kq/r formula voltage depend on distance and the charge. and I know resistor don't change these two quantities. so what is reason of this voltage dropping ?
for show you what is in my mind let imagine a simple circuit with one battery and one resistor. we determine 3 points on this circuit like image below:
I know there is a voltage between A and C , and B and C , but there is no potential difference between A and B. my question is why there is no voltage between these two point ? A has some charge ( so we have q ) and distance to B (so we have r ). my question is why V(A)=V(B) but V(A) is not equal to V(C) ?????????
please help me I can't realize it !
