Explanation:
two disadvantages of series arrangement for household circuits are:
1) series arrangements consume more energy that parallel.
2) in series, if we switch on one appliance, then all the others connected to the circuit also gets on. by this electricity gets wasted.
the factors on which resistance of a conductor depends are:
1) length of the wire
2) area of cross section
3) meterial with which the conductor is made
