What is the Function of a Resistor? Functions Explained with Illustrations

The article describes through schematics how resistors play a vital role in electronic circuits. Here you will be able to find out exactly what is the function of a resistor and also the various uses of resistors in electronic circuits. Resistors come under passive electronic components and are extensively used in electronic circuits. So important are these components that it may be virtually impossible to build an electronic circuit without involving resistors. Basically the function of a resistor is always to oppose the flow of current through it and the strength of this opposition is termed as its resistance. German physicist, Sir G.S. Ohms was able to discover a definite relationship between voltage, current and resistance.
