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.
Two bulb are connected in parallel one bulb glows brightly and other is dim what do you say about their current?
The bulb that glows brightly likely has a higher current passing through it compared to the dim bulb. This could be due to differences in resistance, voltage, or power ratings of the two bulbs.
Why would a cell connected to two bulbs that are connected in series last longer than if the same two bulbs are connected in parallel?
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.
How could you quickly determine if a string of lights is wired in a series or parallel circuit?
In a series circuit, the same amount current flows through each light. And each bulb has a fraction of the total voltage. If you remove one light, the current stops flowing. The makes all of the lights be dark. This type circuit is not used in your house, because every light is designed to operate at 110 volt. In parallel circuit, the voltage is the same for each light. The total current is split between the branches of the parallel circuit. I suggest that you use your computer to search for images of series and parallel circuits. As you look at the drawings, you will see the difference between these two types of circuits.
How can you tell that the strength off both electromagnets is the same?
You can compare the force of attraction or repulsion exerted by each electromagnet on a common object, such as a paper clip. The electromagnet that can attract or repel the object with the same force is likely to have a similar strength. Additionally, you can measure the current flowing through each electromagnet using an ammeter to ensure they are drawing the same amount of electrical power and thus have similar strength.
Why the windings of an ammeter should be of thick wire?
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.
If one of the bulbs in a string of lights is missing but the lights still work what type of circuit connects the lights?
The lights are most likely connected in a parallel circuit. In a parallel circuit, each light bulb has its own separate path to the power source. Therefore, if one bulb is missing or burnt out, the other bulbs can still receive power and continue to work.

parallel circuit.
Are lines that lie in parallel lines always parallel?
That sounds to us like a very likely "yes" .
How do you spell esocieated?
The likely word is "associated" (connected, working with).
Marked with parallel scratches or grooves?
i believe that you are talking about glacial striations
If plant has fibrous root what type of venation do its leaves likely to have?
Leaves of a plant with fibrous roots are likely to have parallel venation, where the veins run parallel to each other along the length of the leaf. This type of venation is common in monocots like grasses and lilies, which also typically have fibrous root systems.
How do you spell accosiated?
The likely word is associated (connected or allied, as with a company).
What geological and climatic conditions are likely to affect slope replacement and parallel slope retreat?
Answer
What is a parallel device?
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.
If one light goes out on a series-parallel connected string do they all go out?
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.
What is used as a diagnostic tool to test the functionality of a defective device such as a power supply but can also be used to test coaxial serial and parallel cables as well as fuses and resistors?
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.
