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?
The positive and negative terminals in an electrical device indicate the direction of flow of electrical current. Electrons flow from the negative terminal to the positive terminal, creating an electrical circuit. This polarity helps ensure that the device functions properly and efficiently.
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?
When two batteries are connected in series in a device, they have to be placed positive to negative to increase the total voltage output. This connection method increases the overall voltage by summing the individual voltages of each battery. Placing them positive to negative ensures that the voltages add up instead of canceling out.
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.
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.
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.
