What happens to other lamps in a parallel circuit if one lamp burns out?

If one lamp in a parallel circuit burns out, the other lamps are unaffected because current still flows through them. Total current in the system is reduced by the loss of the burned out lamp, which will raise voltage ever so slightly. That will have the effect of brightening the other lamps, but that effect is inconsequential unless there is significant impedance in the source or in the path to the lamps.

As you add more lamps to a parallel circuit what will the ammeter reading do?
If the amp meter is in series ahead of the first parallel branch of lamps the meter will read an increase in current.
What happens if there is a short circuit in a parallel circuit?
Incorrect answerThen only one of the lights go out.Correct answerActually ALL the lamps will go out if a short circuit occurs across any branch of a parallel circuit because, if the wiring has been done correctly, a circuit breaker will trip or a fuse will blow to cut off the supply of current to all the lights.The loss of a single lamp indicates a break, not a short circuit.
What happens to the power output of the source if more lamps are connected in parallel?
Nothing will happen to the possible output power of the power source i.e it will not increase. Each power source has its maximum possible output power. Adding more lamps in parallel will result in a drop in the circuit's total resistance which causes the total current drawn by the lamps to increase. Your wires might be burnt as a result so be careful.
What is an electric circuit with components pleased one after the other?
It is a series circuit, where all the lamps (for instance) is on the same wire. If one lamp fails, the rest lamps will also go out.
What is a series diagram?
When the lamps are in a loop, one after the other: we call this a series circuit.
What happens to the power output of each lamp if more lamps are connected in parallel?
The lamps will get dimmer. In a parallel circuit, voltage is constant. Whereas, in a series circuit, amps are constant.
If you unscrew the second bulb in a series circuit while the batteries are in a parallel circuit what happens?
The first lamp will go out. ANSWER: any lamps in series the first or the last if unscrewed will cause all lamps to extinguish no matter whether the source potential is in series or parallel
If both series and parallel circuits have 1 cell and 3 lamps, which type of circuit would be brighter?
Parallel circuit.
If I have a circuit with four lamps each lamp is individually connected across the circuit so that the same current is not flowing through each lamp What type of circuit is this?
Parallel Parallel
If a 12 volt parallel circuit has 3 lamps what is the current?
See discuss.
As you add more lamps to a parallel circuit what will the ammeter reading do?
If the amp meter is in series ahead of the first parallel branch of lamps the meter will read an increase in current.
If each lamp is rated 12v 24w what is the current consumed by each lamp?
2 amperes in a parallel circuit. I = W/V. It is true provided that 12v are delivered to the lamps in parallel circuit. In a series circuit, the voltage is divided among the lamps so that the total current is probably 2 amperes for all lamps.
Are homes on a series circuit?
No. Plugs, lamps and 220 V a.c. items are in parallel with the breakers.CorrectionAll loads are in parallel with the supply voltage, but in series with the circuit breakers or fuses.
What happens to the brightness of the lights when you decrease the number of light bulbs in a circuit?
The brightness of the lights may or may not change depending on the circuit in which they are wired. In a series circuit, all the bulbs (called lamps) will experience the same current flow. The same amount of current will be flowing through each one, and each one will be dropping some amount of voltage. If we remove some of the lamps and reconnect the circuit, the lamps will glow brighter because there is less total resistance in the circuit. The remaining lamps will end up dropping more voltage, and will glow brighter. In a parallel circuit, removing bulbs (or adding them) will not affect the operation of the other lamps in the circuit (providing the voltage source is adequate). We know that each of the lights in a household circuit is wired in parallel, and turning one or more on or off won't affect the operation (the brightness) of any other light that is on.

What happens to the power outputs of the sources if more lamps are connect in parallel?
Nothing will happen to the possible output power of the power source i.e it will not increase. Each power source has its maximum possible output power. Adding more lamps in parallel will result in a drop in the circuit's total resistance which causes the total current drawn by the lamps to increase. Your wires might be burnt as a result so be careful.
When you compare 3 lamps in a series circuit to the same 3 lamps in a parallel circuit connected to the same 12-volt battery which statement is TRUE?
If a lamp burns out in parallel circuit, the other two lamps will continue to glow. If a lamp burns out in the series circuit, the other two lamps will also go out. If 3 lamps are in one series circuit, and one of them goes out, the loop is disconnected.
