Solution
Advantages of connecting electrical devices in parallel with the battery are as follows:
(1) The voltage across each electrical device is the same and the device can take current as per its resistance.
(2) Separate on/off switches can be applied across each device.
(3) Total resistance in parallel circuit decreases, hence, a greater current may be drawn from the cell.
(4) If one electrical device is damaged, it will not affect the other devices connected parallelly, hence the other devices continue to work properly.
