Ohm's Law
Among them, the voltage (which can also be marked as equation is expressed as), is the current, the proportional constant is the resistance. Although the conductor is composed of conductive material, the conductor also has a small resistance. For any conductor, resistor, circuit components, circuits, etc., the definition of resistance equation: regardless of current, voltage, resistance is defined as the voltage divided by the current. In Ohm's law, the resistance is independent of current and voltage. Not every element is subject to Ohm's law. Ohm's law is the result of repeated experiments, only in the ideal situation, will be established. Any element or circuit that follows Ohm's law is called an "ohmic element" or "ohmic circuit" or "ohmic conductor" whose resistance is independent of current and voltage; components or circuits that do not follow Ohm's law are called "non-ohmic components" Or "non-ohmic circuit" or "non-ohmic conductor", the resistance may be related to current and voltage. ...
