Voltage is what they are compared to.
The flow of water is often compared to the flow of electric current. In both cases, the flow is the movement of a substance (water or electrons) from one point to another. The pressure difference in water systems is analogous to the voltage difference in electrical systems, and the flow rate in water systems is similar to the current in electrical systems.
its an open valve system =D your welcome
You can compare:
* The rate of water flow with an electrical current (the thing that is measured in ampere), and* The water pressure with the voltage.
One way to demonstrate a low-voltage electric current using water flow is by creating a simple water circuit with a water pump, tubing, and a water wheel. The water flow represents the current, and you can measure the flow rate to represent the voltage. By observing how fast the water wheel turns or measuring the force of the water flow, you can illustrate the concept of low-voltage electric current through the movement of water.
The flow of electric charge through a conductor is called electric current.
Electric current flows when there is a closed circuit with a pathway for electrons to move from a higher voltage point to a lower voltage point. When the circuit is complete, the flow of electrons creates an electric current.
Current flow
That is called electric current, or simply current.
Compared to molasses, water in the olde mill stream, or traffic on the interstate highway, electric current flows very fast. Compared to the speed of light, in vacuum and in most material media, electric current flows slower.
The flow of electric charges is current.
potential difference make the current to flow. i think this can be compared with mechanical system as fluid flow as a result prssure difference between two points
It is called an electric current.
Yes, an electric current is the flow of charged particles.
A pipe. The volume of water available can be compared to voltage. The diameter of pipe could be compared to resistance with smaller diameter being larger resistance and the flow of water past a point in pipe is equivalent to current flow.
Voltage can be compared with the level to which the tap is opened. (Volume of water) Current can be compared with the speed at which water flows from tap. (Flow of water).
Voltage
DC current
Not really. You can compare them with the analogy of water flowing through a pipe. For water to flow, there must be a pressure difference across the ends of the pipe. An electric current is a movement of electric charges along a conductor. For those charges to move, there must be a voltage (more accurately, a 'potential difference') across the ends of the conductor. So a potential difference is required to cause current to flow.
A current.
In metal conductors, electric current is the flow of electrons.
