State 3 reasons why series arrangement is not used for domestic circuits?

(i) Different appliances need different amount of current, but in series same amount of current flows in through the circuit.


(ii) All appliances work at constant voltage. But, in series the voltage is not constant but current is.


(iii) In series, if any appliance is damaged & it does not work, the whole circuit is broken & none of the appliances work.
