The following figure lists the two types of current sources that are dependent on the direction in which the electrons flow:
Resistance
According to Ohm's law, the flow of current through a conducting is directly proportional to the conductor's voltage. The mathematical equation of Ohm's law is as follows :
I=V/R
Where,
I is the current
Vivo is the potential difference
R is the resistance
Ohm's law states that R in the preceding relation is constant and independent of the current flowing through it is as shown in the following image :
