Potential difference, also known as voltage, is the difference in electrical potential energy between two points. It is measured in volts (V). Potential difference is the force that causes electric current to flow. When there is a potential difference between two points, electrons will flow from the point with the higher potential energy to the … Read more
The electric machine in which mechanical energy is converted into electrical energy is called generator.
The thin short wire used in a live wire of the electric cable to prevent excess current flow in an electrical circuit is called fuse. or, The device used to stop the sudden large flow of electricity is called fuse.
The waste of electrical energy due to the resistance of wire used in electricity transmission is called system loss. or, The loss of electric energy due to the conversion of electric energy into heat energy during transportation is called system loss.
If the demand for electricity in an area is more than the electricity produced, then naturally required electricity cannot be supplied in that area. Then the substations are forced to keep electricity supply off in one area to supply electricity to another area. This process is called load shedding.
An electric charge is the property of matter where it has fewer electrons than protons in its atoms.
Analog signals are continuously changeable voltage or current.
Electric current is the flow of electric charge across a surface, point, or region.
