I know that in a parallel circuit, if you take one lightbulb out, the other one will stay on, but WHY?!?

Question

please explain to me why! Thanks

Answer 1

The other circuits are broken (disconnected). The current continues to pass through the remaining parallel circuits. Draw a picture and imagine water flowing through it.

Answer 2

well it is simple actually but i hope that i can explain to u why, simply in series circuits the current has to be flowing in serie, that means if u have 2 lightbulbs then the same current will flow in both in a series way, and will be the same current by the way, just the voltage will vary according to their different resistanses, but in a parralel circuit, the voltage is the same and the current is the varing variable here, i mean that imagine a simple circuit with those 2 lightbulbs connected in paralle, then the potentioal difference will be the same at the start and end points of the connections for the 2 light bulbs, but the current will be distribut between the 2 branches of the parallel connection according to the vale of their resistances to keep or maintain the potential difference the same, so if u get one lightbulb off the current will stay pass through the second one to make it glow and keep it lihting. i hope that i made things clearer to u now, thx

Answer 3

In a parallel circuit the electricity to both light bulbs is connected to the same + wire and same - wire. That way if one bulb goes out the other one can still draw electricity from the wires. In series the electricity flows through one bulb and then into the other so if the first goes out the electricity is cut off and doesn't get to the next one.

Answer 4

In line you have a bunch of light bulbs. The electricity has to go through all of them successfully to complete the circuit. If you do not complete the circuit, electricity can not flow.
If all the lights are in parallel, they light can pass through any one of them to complete the circuit.

Answer 5

Since the circuits run along side each other, breaking one doesn't stop the flow of electricity.
If they were in series, breaking one circuit would stop the flow of electricity to all the rest.

Answer 6

Because it goes like railroad tracks, with the ties (light bulbs) in between. The bulbs all share the power:

--|--|--|--|--
b b b b
--|--|--|--|--

Remember, a bulb lights by pulling power across the filament in the bulb.

In serial, it's like this:

--b--b--b--b--b--

and if a bulb (or its filament) breaks, everything else doesn't get power.

Answer 7

Same reason that if you unplug your toaster, your alarm clock still works.

Answer 8

Because the other one is magic.
