What is a voltage of a battery?

It is the potential difference between the positive and negative terminals of the battery. The unit of electrical potential is the volt, so the difference in potential between two ponts is also a quantity with units of volts, colloquially called the 'voltage' between the points.


What is it called when positive and negative charges have a potential difference?

Voltage.

Negative and positive terminals are reversed.


What is the voltage reading of positive wire in 110V dc?

You should be asking, 'What is the potential reading of a positive wire....?', as 'voltage' means 'potential difference' and you can't have a potential difference on a wire! The positive wire has a potential difference of +110 V with respect to the negative wire.


What is produced whenever positive and negative ions have been separated?

How do you wire stereo speakers?

Connect a speaker wire to the positive and negative terminals of the speaker, and the same wires to the positive and negative terminals of the amplifier.


What is a positive DC voltage?

A positive DC voltage is an electric potential where excess electrons will flow from negative to positive.AnswerYou appear to be mixing up potential difference (i.e. voltage) with potential. There is no such thing as a 'positive' voltage if you mean 'positive' in the sense of charge! 'Voltage' means 'potential difference', and you cannot have a positive or negative potential difference in this sense. You can only apply positive and negative in this sense to potentials.However, if you mean 'positive' in the sense of direction, then a positive voltage is one that is acting in the opposite direction to a negative voltage within the same circuit. For example, where two batteries have been connected in opposition.


Do electrons move from negative to positive terminals?

Yes

What is the difference between potential difference and potential drop?

There is no difference between potential difference and potential drop. Both terms refer to the difference in voltage (i.e. potential) across a component. Depending on how you look at it, both terms can refer to positive or negative differences, i.e. drop, for instance, can be negative, implying a rise.


A battery has a difference in potential energy between the positive terminal and negative terminal which units express this difference in energy?

That's a difference in electrical potential, not potential energy.It's described in units of "volts".

How can you distinguish between positive and negative terminals?

if you are asking about the terminals of a cell then i can tell you.There is a plus(+) sign near the positive terminal and a minus(-) sign near the negative terminal.


What is negative voltage?

Negative voltage is voltage that is more negative in polarity than the ground of the circuit.AnswerSince 'voltage' is simply another word for 'potential difference', it can be neither negative or positive in the 'charge' sense! These terms can only be applied to 'potential', not to 'potential difference' (voltage).So, the terms 'positive' and 'negative', when applied to voltage, simply indicate sense or direction in which the potential difference is acting. For example, if you decide that a car battery's voltage is acting in the 'positive' sense in the charging circuit, then the alternator's voltage must then be acting in the 'negative' sense -in other words in the opposite direction to the battery.
