A device that uses energy of chemical reactions to separate positive and negative charges?
An electrolytic cell utilizes chemical reactions to generate an electric current that separates positive and negative charges at the electrodes. This separation occurs due to the movement of ions in the solution. The cell typically consists of two electrodes immersed in an electrolyte solution where oxidation and reduction reactions take place.
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 .
What are positive and negative terminals?
Positive and negative terminals are locations on a device or component where electrical connections can be made. The positive terminal typically has a higher voltage potential, while the negative terminal has a lower voltage potential. Ensuring proper connection to these terminals is important for the correct operation of electrical circuits.
When a device uses two batteries why do they have to be placed positive to negative?
Batteries placed in series (which is what you're describing) add their voltages together. Thus two 1.5 volt batteries give 3 volts in series ... IF they point in the same direction. If they point in opposite directions, you get zero volts.
What is Ambipolar Transport Mechanism?
Ambipolar transport is a mechanism that allows for the movement of both positive and negative charges in a material, such as in semiconductors or plasmas. This allows for more efficient control of charge carriers and is essential for creating certain electronic devices like solar cells and transistors. Ambipolar transport is important for balancing charge carriers and ensuring proper device functionality.
What does not create charges but separate them?
A device that separates charges without creating new ones is a capacitor. Capacitors store energy in an electric field by collecting and holding positive and negative charges on separate plates, helping to store and release electrical energy when needed.

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.
A piezo-electric device generates electricity when?
A piezo-electric device generates electricity when mechanical stress or pressure is applied to it, causing a displacement of positive and negative charges within the material. This displacement of charges creates an electric potential difference, which can be harnessed to generate electricity.
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 device creates a potential difference in an electric circuit?
A battery is the device that creates a potential difference in an electric circuit. It establishes an electric field within the circuit that allows charges to move from the positive terminal to the negative terminal, creating an electrical current.
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'.)
What is a rhetorical device used primarily to give a statement a positive or negative slant regarding the topic it is addressing?
spin
What is the device that detects electric charges?
An electrometer is a device that detects electric charges by measuring the voltage or current associated with the charges.
What are the functions of the positive and negative electrodes in a battery?
The positive electrode in a battery is where oxidation occurs, releasing electrons. The negative electrode is where reduction occurs, accepting electrons. This flow of electrons creates an electric current that powers the device.
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.
