(N/A) $1$. In a parallel circuit,the voltage remains the same across all electrical appliances,which is equal to the source voltage. This ensures that each device operates at its rated voltage.
$2$. If one electrical appliance stops working due to a defect or switch-off,the other appliances continue to function because each device has its own independent circuit path.
$3$. The total effective resistance of the circuit decreases when appliances are connected in parallel,allowing for a higher total current to be drawn from the source as needed.
