Hello Student,

Voltage : It can be defined as the potential difference between two points , where one of them has lesser potential compared to the other and flow of electrons is possible between them.

Current : It can be defined as flow of charge through the surface of a conducting body. The direction of current flow is opposite to the flow of electrons. Electrons usually move from a region of lower potential to a region of higher potential.

Hello,

Voltage is the difference in the potential across two terminals in a circuit or device. This potential difference gives raise to current flow.

Current is the flow of electrons. Its conventional direction is from high potential to low potential.

For example, I will place one mug filled with water at high ground and another empty mug at low ground. If I connect these both through a tube, water flows from MUG 1 to MUG 2 at low ground. Here the difference in their height causes the flow of water (like Voltage gives rise to current flow). And the resultant water flow is like the current flow. Instead of water droplets, electrons flow in the circuit.

Hope this helps.

Thanks.
