Current is the flow of electric charge through a conductor, like a wire. You can think of it like water flowing through a pipe. Just as water flows from higher pressure to lower pressure, electric current flows from a point of higher electric potential (voltage) to a point of lower potential.
In electrical terms:
The unit of current is the ampere (A), often shortened to amp. One ampere is the flow of one coulomb of charge per second.
There are two types of current:
To visualize it, imagine a bunch of people walking through a hallway (the conductor), where each person represents a charge, and their movement represents the current. The more people (charges) moving per second, the higher the current.
Does that make sense?
In electrical terms:
- Electric charge is carried by particles like electrons (in most cases) or ions.
- Current is the rate at which these charges flow through a conductor.
The unit of current is the ampere (A), often shortened to amp. One ampere is the flow of one coulomb of charge per second.
There are two types of current:
- Direct Current (DC): The flow of charge always moves in one direction. This is what you get from batteries.
- Alternating Current (AC): The direction of charge flow alternates periodically, like what comes out of your wall sockets.
To visualize it, imagine a bunch of people walking through a hallway (the conductor), where each person represents a charge, and their movement represents the current. The more people (charges) moving per second, the higher the current.
