Electric Voltage Graph
Voltage is the cause and current is the effect.
Electric voltage graph. These are the three basic building blocks required to manipulate and utilize electricity. It is actually the electromotive force emf responsible for the movement of electrons electric current through a circuit. A current voltage characteristic or i v curve current voltage curve is a relationship typically represented as a chart or graph between the electric current through a circuit device or material and the corresponding voltage or potential difference across it. For industrial machinery see industrial and multiphase power plugs and sockets some countries have more than one voltage available.
When beginning to explore the world of electricity and electronics it is vital to start by understanding the basics of voltage current and resistance. You need to know how to investigate how current changes with voltage for a component eg for a resistor or wire at constant temperature a filament lamp and a diode. At first these concepts can be difficult to understand because we cannot see them.
