If you have a 3 bulbs in parallel lets say. If one of those burns out it just means
that there is now an open circuit where the burned out bulb used to be. The two
that remain aren't aware that anything has changed.

∙ 13y agoWhen you connect light bulbs in parallel, each bulb will draw as much amperage as it needs to, and illuminate fully (as long as there is enough supply amperage for all of the bulbs). Unlike hooking them in serial, where the resistance of each bulb is added together, hooking them in parallel allows each bulb to pull its rated current, and thus light fully.

∙ 10y agousually nothing at all. rarely when a lightbulb breaks or burns out it will fail as a short circuit instead of an open circuit, this will pop the breaker causing the other bulbs to go out too but as soon as the breaker is reset they will be fine. this actually happened to me roughly a fortnight ago with the livingroom chandelier.

∙ 9y agoIn a parallel circuit, nothing happens to the other lights they stay in the state they were and at the brightness they were before the light was switched off or burns out.
However in a series circuit ALL the other lights would switch off at the same time.
--------------------------------
The lights in your home are all in a parallel circuit. Turn out one light and see what happens. Each light has its own switch?
--------------------------------------------
If you turn off, or remove, one light from a parallel circuit, then the amount of current the whole circuit requires will be reduced.

∙ 13y agoNothing happens to the light bulb, because there are more than one bulb.

∙ 12y agoNeither. Connecting lamps in parallel subjects each lamp to its rated voltage, so they will each operate at their rated power (therefore brightness).

What happens if the white neutral is not hook ed up at the light?
Then the light won't work!!but it does work..
What happens to pressure in a metal spray when heated up?
It heats up
What are some creative uses for a thermostat?
Hook up a thermostat to your ceiling fan so when your room gets hot your fan will come on!
What would cause a motor to spin faster?
hook up two extension cords, the more cords, the more power.
Is there such thing as a murmade?
Yes there is in another parallel universe. When you grow up, maybe you can invent a machine that allows you to travel to other universes, and can I come with you?
Can you hook up a monitor to the parallel connector?
Yes if it is a old monitor.
How many lights can you hook up on a 600amp low voltage?
If the voltage is right for the bulbs, you can hook up 600 amps divded by the amps taken by one bulb - that gives the number of bulbs. But 600 amp needs very thick wire.
How many batteries can you hook up and still have 12 volts?
You can hook up an infinitive number of 12 volt batteries in a parallel circuit and still have 12 volts.
What is a parallel connector?
A parallel connector, or parallel port, is an interface used to connect a computer to some external peripheral. An example of things that can hook up to a computer using a parallel port include a printer and/or a scanner. More recently, the USB interface has become extremely common and most types of devices that used to commonly hook up via parallel port now hook up by USB instead.
What is the best way to light up 4 mini maglite bulbs at once?
A battery or batteries at the same voltage as the rating of the bulbs. Probably hooked in parallel.
What happens if you add 2 light bulbs to a simple circuit?
A: There is no such a thing as simple circuit if the bulbs are put in series the light will dim if put in parallel both bulbs will light up the same provided the source can sustain the power increase
2002 avalanche the left turn signals dont work the indicator in side flashes but the front and rear lights dont I have checked the bulbs they are OK when I hook up a trailer the trailer lights work?
OK, if the left turn signal light flashes on the trailer when you hook it up I would pretty much think it has to be the bulbs or sockets are bad in your truck. I'd put a new bulb in and seee what happens before anything else. If no help, pull one of the bulbs and put a test light in there and see if it flashes.
If you charge four 50v capacitors in parallel then remove the 50v battery and hook it up to a volt meter will the meter say 50v or 200v?
If you charge four 50v capacitors in parallel then remove the 50v battery and hook them up to a volt meter the meter will indicate 50v.
What happens if you connect two transistors parallel?
If you connect two transistors parallel it will heat up and be damaged.
What happens in Liposuction?
They stick a hose in your but and hook it up to a shop vac
How do you change dashboard bulbs in a Mercedes S320?
make a hook from a coat hanger ,and the cluster pools out,try to hook onto it on the left and right side ,do it slowly,than unplug the wires, some bulbs can be picked up at local stores,warning lights only at dealer.
If you have two 5 watt bulbs connected in series and then in parallel which circuit arrangement will give you brighter bulbs explain your answer?
Brighter in parallel. In series the voltage is divided between the two bulbs, thus the current will only be half so that the power of each bulb will only be one quarter (of 5 watts) in the series set-up.
