Flow of Electron – Electric Current Experiment
Electric current is the flow of electric charge in a conductor, typically due to the movement of electrons in metals. This fundamental concept is key to understanding how all electrical devices work, from a simple torch to advanced machines.
Understanding Electric Current & Flow of Electron:
Electrons are negatively charged particles. When we apply a potential difference across a conductor—say, between points A and B—electrons move from the region of lower potential to higher potential. But the conventional current (as defined by scientists before electrons were discovered) flows in the opposite direction—from higher potential to lower potential.
So, if VA > VB:
-
Electrons flow from B to A
-
Current flows from A to B
And if VB > VA:
-
Electrons flow from A to B
-
Current flows from B to A
It’s important to note: the direction of current is opposite to the flow of electrons.
Real Life Applications:
-
All electronic circuits are built using the direction of conventional current.
-
Devices like LEDs, transistors, and diodes must be placed correctly based on current flow.
-
From electric vehicles to home appliances, understanding current flow ensures proper circuit design.
Key Observations:
-
Current flows from high to low potential, while electrons go low to high.
-
The greater the potential difference, the more current flows.
-
If both ends have the same potential, there’s no current.
Summary Table:
| Case | Electron Flow | Current Flow |
|---|---|---|
| A > B | B to A | A to B |
| B > A | A to B | B to A |
| A = B | No flow | No flow |

Frequently Asked Questions
-
What is electric current?
It is the flow of electric charge, usually due to electrons in a wire. -
Do electrons and current flow in the same direction?
No. Electrons flow from low to high potential; current flows from high to low. -
Why is conventional current used?
It’s a standard direction defined before electrons were discovered. -
Does higher voltage mean more current?
Yes, if resistance stays constant, higher voltage increases current. -
What happens if there is no potential difference?
No current flows. -
Where is electric current used in real life?
In all electronic devices—TVs, fans, mobiles, and more. -
Can I simulate electric current in Dencity?
Yes! Dencity lets you observe current flow with interactive setups. -
Is this topic for Class 10?
Yes, it is part of the Class 10 Science curriculum. -
