# In the topic resistance in series, I read that the current on both sides of a resistor is equal but by using ohm's law we find that resistance is inversely proportional current. How is this possible?

Expert Answer:

### Resistance depends on the nature of material used for making resistors and it's dimensions.
Mathematically, ,
where is the resistivity of material used for making the resistor, l is the length and A is the area of cross section of resistor.
According to ohm's law,
The current flowing through a closed circuit is directly proportional to the potential difference applied i.e.
Here the constant of proportionality is R.
The current flowing through a resistor is nothing but the number of electrons flowing per second. In a series combination
of resistors, the number of electrons flowing through each resistors is same and thus maintaining the continuity of electron flow.
Hence the current in each resistor in series combination is same.
