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.

∙ 12y agoThree lamps in series to a 12 volt battery will each receive 4 volts. Those three lamps in parallel to the same battery will each receive 12 volts. Assuming the resistance of the lamps in both cases is the same (its not, but I'll explain next) the power difference could be a factor of 9 higher in the parallel configuration.
However, the resistance of the lamp is a function of temperature, which is a function of power. Dissipating more power will cause the resistance to rise, so the actual power increase in the parallel case will be somewhat less than 9 times the series case.
AnswerFor a lamp to operate at its rated power, it must be subject to its rated voltage. So, if each of your lamps is rated at 12 V, then the lamps must be connected in parallel in order to operate at their rated brightness.If each of your lamps is identical then, by connecting them in series, each will be subject to a voltage drop of just 4 V and, so, will not be able to achieve its rated power and will, therefore, be very dim.
On the other hand, if each of your lamps have differentpower ratings then, when connected in series, the voltage-drop across each lamp will not be identical, so each lamp will operate at a different brightness -with the lamp with the lowest power rating being the brightest, which is the opposite to what you might expect. This is because the lamp with the lowest power rating has the highest value of resistance and will, therefore, be subject to the highest voltage drop.

What happens to supply voltage if additional resistance is connected in parallel circuit?
No change in supply voltage as additional resistance is connected in parallel circuit.
Light bulb in parallel circuit brightness?
Two bulbs connected in parallel are brighter than two connected in series. The resistance of the circuit is lower, electrons can flow more easily.
Why does an electric bulb not become dim when another bulb of the same power in a parallel circuit is switched on?
The reason that neither lamp is affected by the operation of the other is that each one can "see" the applied voltage whether the other is on or not. Each is "directly connected" to the source, a lamp's operation is unaffected by the other lamp. Trace the flow of current from the source through a lamp and back to the source. The other lamp is not in that circuit, and it will not have an effect on the lamp being inspected. This is the nature of a parallel circuit. Each branch in a purely parallel circuit is directly connected to the source and operates as it does without any regard whatsoever as to what may or may not be connected in parallel with it.
How are a Genecon and a Battery similar when they are connected to a circuit?
i need help
What are the changes take placein the volt meter connected to the series and pararrel circuits?
The essential difference between a series circuit and a parallel circuit is the way in which the components are physically connected. In a series circuit there is just a single path that electricity can take, whereas in a parallel circuit there are two or more different paths.
What is the equivalent resistance of the parallel circuit you have connected?
In principle, it is infinite. I have not connected a parallel circuit in ages.
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
Does batteries connected in parallel increase the current capacity to the circuit?
If each battery is identical, yes.
Which part of the battery is an amp connected to in a car?
An ammeter must be connected in parallel to the circuit. If you do not understand the difference between parallel and series connection then you should leave it to a competent mechanic/electrician.
How does the voltage of a double battery compare to the voltage of a single battery?
The voltage depends on how the two batteries are connected to one another. If they are connected in a series circuit (positive end to negative end) the voltage will double. If they are wired in a parallel circuit, (It
How are the loads in parallel circuit connected?
Parallel to each other.
What is a circuit in which loads are connected side by side?
A circuit in which loads are connected side by side is known as a parallel circuit.
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
What happens to supply voltage if additional resistance is connected in parallel circuit?
No change in supply voltage as additional resistance is connected in parallel circuit.
What is a circuit connected in a single path?
A circuit connected in a single path is called a series circuit. In a series circuit, the current flows through each component in sequence, providing only one path for the electricity to follow. If one component fails, the entire circuit is disrupted.
In a circuit does lamp gets dimmer if more lamps with same battery?
this depends on 1. whether the extra bulbs are being connected in parallel circuit or in series with each other, and 2. the power rating of the battery. supposing the battery power rating is greater than all the individual bulbs put together, the bulbs will glow the same maximum intensity if they are connected in parallel, and will become dimmer if connected end to end i.e in series.
How should a ammeter and voltmeter be connected in circuit?
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
