ELECTRICAL ENCYCLOPEDIA

What is a Resistor? http://en.wikipedia.org   A resistor is a two-terminal passive electronic component which implements electrical resistance as a circuit element. When a voltage V is applied across the terminals of a resistor, a current I will flow through the resistor in direct proportion to that voltage. This constant of proportionality is called conductance, G. The reciprocal of the conductance is known as the resistance R, since, with a given voltage V, a larger value of R further "resists" the flow of current I as given by Ohm's law: Resistor Symbol http://www.rapidtables.com   Click the title above to view the Resistor schematic symbols of electrical & electronic circuit diagram - resistor, potentiometer, variable resistor.
