Voltage Current And Resistance Explained
The amount of current in a circuit depends on the amount of voltage and the amount of resistance in the circuit to oppose current flow.
Voltage current and resistance explained. The unit of voltage is the volt which is a measure of el. 1 volt 1 joule coulomb. Ohm s law is explained using the water model. Voltage can exist without current.
For this reason the quantities of voltage and resistance are often stated as being between or across two points in a circuit. This means that if the voltage is high the current is high and if the voltage is low the current is low. This electronics video tutorial provides a basic introduction into voltage current and resistance. 1 ampere 1 coulomb second.
Current is the effect voltage being the cause. Ohm s law describes the relationship between voltage current and resistance. In a linear circuit of fixed resistance if we increase the voltage the current goes up and similarly if we decrease the voltage the current goes down. Resistance is a material s tendency to resist the flow of charge current.
Current cannot flow without voltage. The three basic principles for this tutorial can be explained using electrons or more specifically the charge they create. Voltage is the force or potential difference acting on the current to flow from one point to another in a conductor. Voltage current and resistance in circuits explained definition animation video for kids voltage current and resistance the relationship between voltage cur.
V or volts or voltage. Here too one can get an explanation with the help of the water model. Voltage is the difference in charge between two points. The above illustration will help you to understand ohms law the relation between voltage current and resistance.
Just like voltage resistance is a quantity relative between two points. Current is the rate at which charge is flowing.
