In a parallel circuit, more power is provided to the lights. Power = V2/R . The resultant resistance of the circuit is lower, and the potential difference is not divided as in a circuit in series. Thus, lights in parallel burn brighter.
Additional InformationA lamp's power rating only applies at its rated voltage. Because the voltage across each branch of a parallel circuit is the same, each lamp can be supplied with its rated voltage and, therefore, will operate its rated power. In a series circuit, the voltage appearing across each lamp will be considerably lower and, so, the lamps will not operate at their rated powers.in your question you mention dimmer... so i have to assume you mean a LED or Light bulb (or anything to do with a light as indication).
As you have learn in Electric or Science 101...
V=IR (Voltage = Impendence x Resistance)...........(1)
Rn = R1 + R2 (Resistance in Series = First resistor + Second resistor)........ (2)
Rn = [1/R1] + [1/R2] (Resistance in Parallel = First resistor in parallel + Second resistor in parallel) ........ (3)
refering to the above 3 formula.
in a basic circuit if you link a battery to the LED or light.
eg.
Battery source = 3.0v DC
R = constant 10 ohm from LED (just as a example, i know there is know LED running at such high ohm)
A = unknown... (but can be used as a reference to the light's brightness intensity; higher AMP=brighter,draw more power from battery/ lower AMP=dimmer, draw less)
in case of series
3v=(10+10)A
3/20=A
a=0.15A
in case of parallel
3v=([1/10]+[1/10])A
3/[2/10]=A
30/2=A
a=15A
so from the result you see there is a big difference between the amperage between 2 circuits....
because current divides in parallel connectins
AnswerA lamp only operates at its rated power when supplied with its rated voltage. Lamps in parallel share the same supply voltage (the supply voltage is common to each branch); if this voltage is the lamps' rated voltage, then they will each operate at their rated power.
Way too unspecific to answer properly. If you are talking about at the end of a circuit onstead being for instance a part of a parallel on the circuit then it does not matter what type of circuit it is, only the final yields of voltage and amperes will matter.
Parralel however is both more energy efficient and has less resistance because of the alternate paths that are available.
AnswerFor a lamp to operate at its rated power (therefore, at its rated intensity), it must be supplied with its rated voltage. So, as long as an individual lamp is subjected to its rated voltage, it doesn't matter how it's connected. Incidentally, a parallel circuit is no more energy efficient than a circuit.
In a parallel circuit - the power is shared equally between each 'branch'. With a series circuit - the first bulb in line takes the bulk of the power.
AnswerIt's a complete myth that 'the first lamp in line', in a series circuit, 'will take the bulk of the power'!! The correct answer is as follows:Lamps will only operate at their rated power when subjected to their rated voltage -which is why you will see both figures shown on the glass envelope (e.g. 60 W / 230 V or 60 W / 120 V, etc.).
If you connect lamps in parallel, because each branch is subject to the same voltage (i.e. the supply voltage), each lamp has the same voltage applied and will operate at its rated power.
If you connect lamps in series, the supply voltage will distribute itself as a series of voltage drops where the sum of the voltage drops will equal the supply voltage. So none of the lamps is subject to its rated voltage, so none will operate at its rated power -i.e. they will be dim!
A: It does not mater how it is connected a bulb will light up the same if the same power is available.
If both configurations use the same bulbs and the same power supply,
then the bulbs shine brighter in parallel than they do in series.
If the bulbs have different brightnesses in a series circuit, then they must have different power and/or voltage ratings.
A series circuit has one way a parallel circuit has more than one way
If you are referring to an electrical circuit, a series circuit is wired in such a way that if one object is removed from the circuit, the circuit is broken and everything within the circuit loses power. In a parallel circuit different components of the circuit can be removed without disabling power to the rest of the devices within the circuit.
It depends on the circuit. If it is a constant-current circuit, any light bulbs connected in parallel with it will become brighter. If it is a constant-voltage circuit like a typical household circuit, nothing will happen. Any connected in series with it will go out.
The series circuit has one wire, while the parallel circuit has two wires. And if you connect the extra wire its dim because your taking away electrons and energy flowing through the main circuit -Hope this helped:D The difference is that series circuit has one path but parallel has more than one path. -hope this helped!:D ~Bunnii Boo
That is a parallel circuit. Each bulb is wired directly to the power and not through each other. A Christmas tree light set is an example of a series circuit, and often up to 3 series circuits in parallel. Because the sets are wired in parallel, a missing bulb in one of the series sets only affects that one set, and thus 2/3 of the lights may still work.
then the other light bulbs in the circuit go out. However, in the case of modern Christmas tree lights in series, the bulbs are designed to short out when they blow, so that the other bulbs do not go out. They do get brighter, however, and this can lead to cascade failure, but that is why there is often a fuse in the plug.
Parallel connections will draw more current than equivalent lights connected in series, so the parallel configuration will be brighter.
series circuit
Parallel circuit.
No, electric lights come in both parallel and series circuit.
Parallel. One light burning out does not stop all current flow to the other lights.
Yes you would use a serial circuit You would use parallel circuit lights for a Christmas tree because if you used series circuit lights, and one of the bulb blows, the rest of the bulbs will go out. But with parallel circuit lights, if one bulb blows the rest of the bulbs will remain their brightness.
both
There are four types of circuit: series, parallel, series-parallel, and complex.
In a series circuit, if any one bulb goes open the rest of the lights will go out. The current flow in a series circuit is common throughout the whole circuit. In a parallel circuit when one bulb goes open the rest remain on due to the configuration of a parallel circuit.
um.. a switch is a part of a series circuit because parallel circuits don't have switches
Removing any bulb breaks the continuity of a series circuit, stopping the flow of electrical current. Removing a bulb in a parallel circuit does not interrupt the current flow, so the remaining lights continue to conduct electrical current.
A series circuit is actually in series, but a parallel circuit, is Parallel
