What are the advantages of connecting electrical devices in parallel with the battery instead of connecting them in series?

Explanation

The advantages of connecting electrical devices in parallel with the battery instead of connecting them in series are as follows:
( 1 )A parallel combination/ circuit is helpful when each device has different resistance and reqUires different current for its operation. as in this case the total resistance of the circuit is reduced due to which the current from the battery is high and hence ear.h electrical device can draw the reqUired amount of current.
ThiS is not so in a series combination/ circuit because total resistance increases too much in series circuit due to which the current from the battery is low and the same low current flows through all the devices. irrespective of their resistances and hence devices cannot work properly.
( 2 ) In a parallel combination/ circuit each electrical device gets the same p.d. (potential difference) across it as that of the battery due to which all the devices work properly.
While in case of a series combination/ circuit the devices do not get the same p.d. as that of the battery because the p.d. is shared by all the devices connected in series.
( 3 ) In a parallel combination/ circuit if one electrical device stops working due to some defect, then other devices are not affected. They continue to work without any problem.
On the other hand, in a series combination/ circuit if one electrical device stops working due to some defect, then all other devices also stop working as the whole circuit is broken.
( 4 ) In a parallel combination/ circuit each electrical device has its own switch due to which it can be turned .ON. or turned .OFF. independently without affecting other devices.
But in a series combination/ circuit all the electrical devices have only one switch due to which they cannot be turned .OFF. or turned .ON. independently.
