If a 12 volt parallel circuit has 4 lamps and each lamp consumes 1 amp what is the resistance of each lamp?
Assuming you mean the 4 lamps are in parallel with each other: the total voltage drop across each lamp is still 12V. As we know that V= IR (Voltage = I Current times Resistance) 12 = 1 x R so Resistance = 12 Ohms for each lamp.
Why does one bulb make the others go out in a series circuit?
because current in parellel divides unlike in series if one fails all will failsAnswerThe parallel circuit's load current doesn't 'divide'. It's the other way around! Each branch draws an individual current which then 'combine' to form the circuit's load current. However, the reason that the remaining lamps connected in parallel always work, even if one fails, is because each branch of a parallel circuit is subjected to a common supply voltage.
Why do you connect electrical lamps in series?
If you are referring to house wiring, then you don't normally connect lamps in series with each other; they are normally connected in parallel with each other. When lamps are connected in parallel, each lamp is subjected to the same voltage; providing this is the rated voltage of each lamp, them each will operate at their rated power.If you did connect lamps in parallel, the you would find that the lamps with the higher power ratings will be dimmer than the lamps with the lower power ratings -which is not what you might expect!
What must be applied to an electric charge to make it flow in a circuit?
There are many complex explanations for current flow in electronics. The answer below describes the basic requirements without including great detail. For a more academic discussion, you are advised to look at relevant sections of text books on electrical and electronic engineering. In order for electrical current to flow, there must be two things: 1) A voltage (sometimes referred to as a "potential difference"). The voltage can be created by a battery, a generator, a solar cell or a mains voltage outlet. 2) A complete circuit. This must include conductors such as wires that start at the positive terminal of the voltage source and at the far end, return to the negative terminal of the voltage source. Other components such as lamps, resistors and switches can form part of the complete circuit. We must have a voltage for current to flow because without it, there is no "electrical force" to cause the current to flow. We need a complete circuit so that the current can flow from the positive of the voltage source, through conductors and return to the negative of the voltage source. Current will flow through any complete circuit. If a switch is part of the circuit, when it is open, no current can flow because the circuit has been broken. When the switch is closed, the circuit is complete and current will flow once again. Therefore, it is possible to have a voltage without a current (switch open, for example) but it is not possible to have a current without a voltage. NB: Mains electricity is alternating current. It follows the same principles as the DC examples mentioned above although there is a changing voltage rather than a constant voltage.
What is the voltage rating of lamps on a parallel circuit with a 12 volt battery?
If the lamps (the technical term for light bulbs) are the "correct" ones, the 12 volt battery is all there is and all the lamps are connected in parallel, the lamps are rated at 12 volts. There are a flock of assumptions, but why not pick an easy example to make a case? The average vehicle has a 12 volt electrical system. Car people throw that number around all the time. But the actual voltage on the power buss when the engine is running is in excess of 13 volts because of the alternator that keeps the battery pumped up and runs the electrics. All the lights on the rig (and they're all connected in parallel) are run off the 12 volt buss. Ask an auto person what a light bult for a car is rated at and the answer may very well be "12 volts" (the normal expression of the buss voltage). Could it be said the lights are rated at 13 volts (or 14 volts) because that's the actual working voltage of the system with the engine running? Sure. Why not. Whatever works. The lights will work at a higher voltage (15 volts) , but they will be far more susceptable to damage by vibration and shock. And they will certainly have a shorter life if the voltage is ramped up. Keep it simple and say that lamps designed to work in a 12 volt system are rated at 12 volts. Don't go into an auto parts store and ask for a lamp rated at 14 volts. You'll probably just confuse the parts helper. The folks who make the light bulbs know the drill, know the normal range of voltages over which the light will be working. They'll optimize their designs to produce fairly priced but well-performing pieces that stand up nicely over a modest range of voltages. And that includes some voltages a bit above the actual "rating" of the lamp.
If three lamps are connected in series to a 6 volt battery how many volts are impressed across each lamp?
In a parallel circuit, Voltage is constant through out the circuit. Thus, the voltage across each lamp is 6-volts.
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.
How does the number of bulbs affect the amount of electrisaty in a circuit?
Adding additional lamps has no effect on the supply voltage supplied to you home. If the lamps are connected in series, then the sum of voltage-drops appearing across each lamp will equal the supply voltage. If the lamps are connected in parallel, then the voltage across each lamp will equal the supply voltage.
Why are lamps connected in parallel?
If lamps were connected in series, if one light blew out, the entire system would shut down.Although this is true, the main reason is that, by connecting each lamp in parallel with each other, each is subject to the same voltage*. And the power rating of a lamp only applies when it is subjected to its rated voltage.(*The voltage across each branch of a parallel circuit is identical.)
Why are house lights parallel?
in parallel series if one of the light stops working also the remaining lights can workAnswerLamps will only operate at their power when they are subjected to their rated voltage. The only way of subjecting all your lamps to the same (rated) voltage, is to connect them in parallel (because the same voltage appears across each branch of a parallel circuit).The fact that the other lamps will continue to work if one lamp fails is a bonus!
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.
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 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.
How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a simple circuit?
The brightness of each bulb in a parallel circuit is the same as the brightness of a bulb in a simple circuit. By Kirchoff's voltage law, each element of a parallel circuit has the same voltage drop across it. With the same voltage, the same type of bulb will dissipate the same power, and have the same brightness.
What happens to the brightness of the bulbs in a parallel circuit?
A lamp's rated power only applies when the lamp is supplied with its rated voltage. If you connect the lamps in series, with the same supply voltage, then the lamps are no longer subjected to their rated voltage and, so, will not operate at their rated power.
Why are parallel circuit better idea than putting them in a series?
It depends, of course, what 'them' are! But, for most electrical loads, their power ratings only apply when they are subjected to their rated voltage (you may have noticed that lamps have both their rated power and their rated voltage printed on their glass envelope -e.g. 100 W / 230 V). The only way to subject a number of different loads to a specified rated voltage is to connect them is parallel, as the voltage across each branch of a parallel circuit is equal to the supply voltage.
What is the advantage of using series parallel connection?
Series connection has only a single path through which the electron can travell,where as the parallal connection has many paths to travell the electrons.So in a serise connection if one of the component of the circuit is switched off,every other component of the circuit will be switched off. Fairy lights are usually series connected. The main voltage is divided across the number of lamps. So each individual lamp is low voltage.
