Question

Just a conceptual question . I understand that in a circuit, capacitors acquire a voltage or potential difference due to charges being transferred in current from one plate through the battery to the other plate which causes a positively charged plate and negatively charged plate thus a voltage and if in parallel with the circuit the voltage of the capacitor will increase until it is equal to the emf of the battery . Now resistors are confusing , I realize ohms low IR=V and in series the current is the same parallel voltage is the same etc etc . Now, what I want to know is how if current is run through a resistor and the current going into the resistor is equal to the current going out does it have a potential difference ? How is there a difference in charge between the two wires of a resistor if the current is conserved ? I don't understand how there can be a difference in charge if the amount of particles is conserved on both sides . Help ? Thanks Just a conceptual question .

Explanation / Answer

when current is passing through a resistor across it ends we get potential drop.it is connected to battery has potetial.here battery is supplying charges continuosly na.charge conserved possible only at junction.At junction ,sum of the currents entering is equal to sum of the currents leaving.this is kirchhoffs law.
