How Current Flows In A Circuit
This may be a slightly advanced video on electricity and.
How current flows in a circuit. Current flows in the opposite direction of the electron flow. A flow of positive charges gives the same electric current and has the same effect in a circuit as an equal flow of negative charges in the opposite direction. Alternating current ac and direct. Conventional current is the flow of a positive charge from positive to negative and is the reverse of real electron flow.
Electrical current is measured in amperage or amps. Conventional current assumes that current flows out of the positive terminal through the circuit and into the negative terminal of the source. Electrical current exists in two types. In a simple circuit current flows from the positive terminal of the battery to the negative terminal of the battery while electrons flow from the negative terminal of the battery to the positive terminal of the battery.
The term current refers to the simple flow of electrons in a circuit or electrical system. You can also liken electrical current to the quantity or volume of water flowing through a water pipe. Water current is the rate at which water flows past a point on the water circuit. This was the convention chosen during the discovery of electricity.
In this video we will understand how electricity electric current flows through a simple circuit. Current is the rate at which something flows. Electron flow is what actually happens and electrons flow out of the negative terminal through the circuit and into the positive terminal of the source. As such current is analogous to the number of gallons of water flowing into along and out of a slide per unit of time.
