Resistance in Series and parallel


Resistance is only component availbale which converts current into voltage and voltage into current.


Resistance in Series:-

In Series resistance are additive and are as described below:-

If there are resistances are R1, R2, R3, R4 ----- RN are connected in Series then equivalent resistance is given as 

R (Eq.)= R1 + R2+ R3+ R4+ ---------------------+RN

Series resistance is known as voltage divider circuit in which voltage get divided but current remains the same.
Whenever resistance is added in series then equivalent resistance is getting increased.

Resistance in Parallel:-

If there are resistances are connected in Parallel then equivalent resistance is given as :-

If there are resistances are R1, R2, R3, R4 ----- RN are connected in Series then equivalent resistance is given as 

        1      =   1   +   1   +    1     +    1    +  ------------- +    1 
    R(eq.)       R1     R2      R3         R4                              RN
Then parallel circuits are current dividers. They have same voltage in Parallel but current get divider.
Note that the equivalent resistance is always less than the smallest resistor in the parallel network so the total resistance,  Equivalent resistance will always decrease as additional parallel resistors are added. Parallel resistance will give conductance which is described by G and unites are Siemens S.
