|
there is only one path for the current to take

|
|
current from each bulb has its own path

Detailed explanation-1: -Three identical electric bulbs are connected parallel to each other. On connecting their combination across a source of emf having stabilized voltage and negligible resistance, all bulbs glow with full brightness. Suddenly a bulb fuses. The other bulbs will glow.
Detailed explanation-2: -In parallel circuits, each light has its own circuit, so all but one light could be burned out, and the last one will still function.
Detailed explanation-3: -In a parallel combination, even if one of the bulbs blows out, the other bulbs will continue to glow as electricity still has a closed circuit to flow.
Detailed explanation-4: -What would happen to the intensity of other light bulbs if one of them burn out? Since a parallel connection provides them all with the same voltage source, they will all operate independently. The one that burns out will go out; the other two will continue to operate at the same power and light output.
