Current, Voltage and Resistance

The flow of electrons is called current (I). Current is the amount of electrons flow per unit of time. The repelling force called voltage (V) refers to the amount of potential energy between two points on a circuit. An opposition to flow of current in a path then that is called as resistance (R). The relationship between current, voltage, and resistance is described in Ohm's Law. This law states that the current flowing in an electric circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the material.
