## Find Value of Resistor by Resistor Color Code Resistor Band Color

How to find the value of unknown resistor ? The electronic color coding is used to find out the value or rating of electronics component ,usually for resistor but also for capacitor ,inductor , diode and others There are many types of resistor which ...Read More

## Conductance ( G )

Conductance is the reciprocal of resistance ( R ) .Thus                G  =  1/R  The Unit of Conductance is mho          To purchase Electrical products Click Here You may also read Kirchoff’s laws Fleming’s Left hand rule Kirchoff’s Voltage law Electrical power and Resistance ...Read More

## Ohm’s Law

The current flowing through the conductor is proportional to the applied voltage and its remain constant, if the temperature and other condition remain constant .Thus           Current =Voltage applied /Resistance of circuit         Resistance =Voltage applied /Current in the circuit        Potential across resistance ...Read More

## Law of resistance Resistance

Resistance of conductor depend upon Length of conductor —-its varies directly with the length; Cross-sectional area of conductor —its varies inversely with the cross-sectional area of conductor Its resistivity i-e the nature of composition etc of the material of which conductor is made up ...Read More
