                                                                                       ELECTRICITY

              If    is the equivalent resistance and V=IR


              Hence,


              IR=I(R +R +R )

              Some important points regarding series combination of resistors are


              as follows:






               The equivalent resistance is equal                The equivalent resistance is thus
                                                                 greater than the resistance of either
               to   the    sum     of   the    individual        resistor.    This   is   also    known      as
               resistances.
                                                                 maximum effective resistance.






               The current through each resistor                 The potential difference across each
               is same.                                          resistor is different.
