A device that uses energy of chemical reactions to separate positive and negative charges?
okay slender man will kill you if you dont know
Why is there a positive and negative terminal in electical device?
there are positive and negative terminal in electrical device who operate on dc power supply because they wont work if the connection is reversed. but devices who operate on ac usually dosenot have polarity marks .
A prism is a device that separates white light waves into the colors of visible light Which of the following processes allows a prism to work?
Refraction
The property of an electrical device that permits storage of electrically separated charges when potential differences exist between the conductors is called what?
Capacitance.
Why is it possible to measure an electric potential across the terminals of a dry cell?
Batteries are a voltage storage device that hold a voltage potential until used. By using a volt meter you can find the stored voltage by placing the leads of the meter across the battery's positive and negative terminals.

Properties of charges?
There are three different types of charges: positive, negative, and neutral. All three have their own specific properties having to do solely on atomic particles. In positive substances or ions, you will have a large number of protons which have a positive charge to outnumber the charge of the electrons which give off a negative charge, and lastly you have neutrons which don't really give a substance anything other than mass, to get a neutral charge the protons and neutrons must be in equal amounts to cancel out each others' charges.
What determines which one of the terminal of a rheostat in positive when connected in a series?
Electron flow is from negative(-) to positive(+), the rheostat would have to be on the negative side for the device being controled, before the device, e.g. light bulb.AnswerIt doesn't matter. Rheostats don't have positive or negative terminals.

What is meaning of series and parallel connection?
If you connect a device like a LED or a speaker in series, that means that you connect the positive terminal of one speaker/LED to the negative terminal of the other speaker/LED and apply the audio/voltage to the remaining positive and negative terminals. When you connect devices this way, that means that both of the speakers/LEDs are getting the exact same current, but different voltages depending on the position in the parallel circuit. If you connect a device in parallel, then that means that the device's positive and negative terminals are connected to the other device's positive and negative terminals, and then voltage is applied to the positive and negative terminals of the devices respectively. This means that the devices are getting the same voltage but the current varies and is highest at the positive connection and lowest at the negative connection. (The voltage that each device is getting is determined quite easily by doing the sum 'input voltage / number of devices'.)
Why 0.3 voltage in germanium diode?
the reason for 0.3V as barrier potential in Ge is:- Electrons near the junction drift into the P region and recombine with holes. At the junction, the P-side has a layer of negative charges or negative ions (since p-type material is electrically nuetral addition of an electron makes it a negative ion). At the junction, the N-side has given up electrons thus creating holes i.e. it has positive charges or positive ions.This ion build up creates an area that is depleted of any conduction electrons or holes i.e. it has positive charges or positive ions cancelled out by negative charges or negative ions This ion build up creates an area that is depleted of any conduction electrons or holes. This represents a potential difference of 0v to 0.3v volts Ge diodes Semiconductor devices are controlled by controlling the depletion region of the device. The potential difference is called the barrier potential. It's basically what makes the semiconductor work, so its a really good question.
What is a rhetorical device used primarily to give a statement a positive or negative slant regarding the topic it is addressing?
spin
In a battery using device the current would flow from the Negitive end through say a led light then find its way to the Positive end of the battery completing the transition?
NO. By tradition and usage : current flows from positive to negative. In reality : electrons flow from negative to positive.
Why is there a plus and a minus side on a triple a battery?
There is a plus and minus side on all batteries to indicate the polarity of the battery - positive (+), negative (-), this way one knows which part to match with the device. Plus on the battery has to match the plus on the device and same for the negative in other for the device to function.
Is white wire positive?
Generally, white wires are positive. Red is usually negative. However, the construction of the electrical device could be different. It is best to check the instructions.
Which fallacy is a rhetorical device used primarily to give a statement a positive or negative slant regarding the topic it is addressing?
Slanters
What is the white wire for on your 80cc bike motor kit?
It is an electrical output wire. Connect white to the positive of a device and the negative on the device to ground. Only works then motor is running
