Resistance and Conductance - Basic Concepts A resistor is an element for which there is a linear relationship between the voltage across it and the current through it, so that V = I x R (Ohm’s law) R V V R V V I Power 2 = = = ( 29 R I IR I 2 = = Series Resistors (Connected in tandem) The equivalent overall resistance is equal to the sum of the individual resistances. R Eq = R 1 + R 2 + R 3 + …. . + R n Parallel Resistors (Connected so that they all share both the top and bottom terminals) For resistors in parallel, the reciprocal of the resistances are added to result

Hence, the above equation can be restated as follows: For resistors in parallel, the equivalent overall conductance is equal to the sum of the individual conductances. n G ....
