An electric current is a continuous flow of charged particles, typically electrons, moving through a conductor. Unlike the unidirectional flow of water or air, the direction of the current is determined by the direction of the flow of the charges.
This flow of charged particles is what allows electrical energy to be transferred from one object to another. We can observe this phenomenon in various devices like batteries, light bulbs, and power lines.
The amount of electric current passing through a conductor is determined by various factors, including the voltage of the source, the resistance of the conductor, and the resistance of the devices connected to the conductor.
Key points about electric current:
It is a measure of the amount of charge flowing through a conductor per unit of time.
It is measured in amperes (A), where 1 ampere is the flow of 1 coulomb of charge per second.
Electric current is always positive, meaning that the charges flow from a higher potential to a lower potential.
Electric current is affected by both the voltage and resistance of the conductor.
It is an important concept in understanding the flow of electricity in various devices and circuits
