Write the disadvantages of series circuits for demostic wiring.

Explanation

( 1 )In a series circuit the current is constant throughout the electric circuit. So it is obviously impracticable to connect an electric bulb and an electric heater in series because they need currents of widely different values to operate properly.
( 2 )In a series circuit when one component (or electrical appliance) fails due to some defect, the circuit is broken and none of the components (or electrical appliances) works.
( 3 ) In a series circuit all the electrical appliances have only one switch due to which they cannot be turned ON or OFF separately.
( 4 )In a series circuit electrical appliances of different power ratings do not get the same voltage (220 V) as that nf the power supply line because the voltage is shared by all the appliances. The appliances get less voltage and hence do not work properly.
