ameter has a low resistance so if it is placed in parallel with the load then it will experiance voltage as much as the load and according to equation
power=v2/r
the power will be very high as high v or low r both favors for a high power dissipation .
but on a series combination most of the voltage drop will be on load the ameter will not have a high power dissipation
Parallel circuit
This question looks like one that has been asked by a high-school teacher with very little knowledge of electrical science, and who doesn't realise that the resistance of a lamp changes appreciable between when it is cold and when it is hot! (Either that, or he is being devious!)So, as stated, this question is not straightforward, because incandescent lamps that operate at their rated voltage and power have a 'hot' resistance that is around 15 - 20 times their resistance when cold. Lamps in series are not subject to their rated voltage and, so, their resistance will be relatively low in comparison. So, what the question comes down to is whether the combined (high) resistance of lamps in parallel (i.e. half the resistance of one of the lamps) higher or lower than the combined resistance (low) of the same lamps connected in series (twice that of one of the lamps)? You could find this out experimentally, but I'd be inclined to believe that the two lamps connected in parallel are more likely to have the higher resistance and, therefore, the cell supplying them would last longer -in other words, opposite to that in your question!Now, if you simply used two resistors (whose resistance doesn't change appreciably with temperature) then the two connected in series would definitely have a higher resistance (twice) than if they were connected in parallel (half), and they would draw less current and the cell would last longer.
They can be. The electronics used will vary between models, but with the vast amount of systems used in modern cars (lighting, environmental controls, media players, computers, etc.) you would be unlikely to find a car that doesn't.
Of course. A good voltmeter can be applied across anything, since its impedance is high and its presence has no effect on the operation of the circuit. When it's connected across a variable resistor, the voltmeter most likely reveals a changing voltage as the resistor is varied.
really likely
because lots of current is likely to be flowing through them.however a shunt ammeter is easier to build than the direct ammeter as described above. in a shunt ammeter you use an ordinary meter wound with fine wire and put a small value shunt resistor across it to take almost all the current.
That sounds to us like a very likely "yes" .
Parallel circuit
parallel
The likely word is "associated" (connected, working with).
The likely word is associated (connected or allied, as with a company).
Answer
If one light goes out on a series-parallel connected string, all of the lights in that particular series string will go out. The other parallel strings will not be affected. If you are asking about Christmas tree lights, please note that most modern low voltage bulb designs make the bulb short out, rather than open, when the filament burns out. This keeps the other bulbs in that series string on, although they now have more power and are more likely to also burn out.
There are several meanings of parallel device. It can mean having two or more computers working on the same problem at the same time. This is called parallel computing. Or it can mean any device hooked up to the parallel port on a computer. Parallel ports are fairly obsolete, so you are less likely to see this version of parallel device in the future.
You likely mean a multimeter. A multimeter tests voltage (voltmeter), current (ammeter) and resistance (ohmmeter). You would need a high impedance one to help prevent blowing sensitive circuits, and digital ones tend to be high impedance.
