Definition of Current
Current is the flow of electric charge. In a conductor, it is the movement of electrons.
Current can be:
- Direct Current (DC): The flow of electric charge is constant in one direction.
- Alternating Current (AC): The flow of electric charge periodically reverses direction.
Formula for Current
The formula for current is defined by Ohm’s Law:
I = V/R
Where I represents the current, V is the voltage, and R is the resistance.

Unit of Current
Electric current is the flow of electric charge in a conductor. In our daily lives, electric currents play a pivotal role. Whether in classrooms or homes, understanding the flow of current is essential. Scientifically, electric current refers to the movement of charge in circuits, sometimes carried by both ions and electrons. The unit of current, known as the Ampere (A), enables us to quantify this flow. Let’s learn about it all.
