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.

How can you measure electric potential and electric current?
Potential . . .Always measured as a potential difference between two points.The most practical way to do that is with a voltemeter connectedin parallel with any circuit between the two points.Electric current . . .The most practical way to measure current is with an ammeter connectedin series in the path of the current.
What is potencial difference measured in?
The unit of measure is the Volt Potential difference is basically electrical "pressure" (an excess of electrons). Volt.....The unit of electric potential. Named after the Italian physicist Alessandro Volta (1745- 1827). The potential difference is the difference in charge at the poles of a current source The volt (symbol: V) is the SI derived unit of electromotive force, commonly called "voltage". It is also the unit for the related but slightly different quantity electric potential difference (also called "electrostatic potential difference"). ... en.wikipedia.org/wiki/Volt
Does a electric meter measure the number of protons in a current?
Electric meters measure kilowatt hours.
What instrument measures electrical energy?
BTUAnswerBTU AnswerBritish thermal unit; BTU
How many lumens equal one volt?
No telling. Volts are a measure of electric potential. Lumens are a unit for light intensity. Different bulb types with the same input voltage will yield different lumens out.
What are volts measure of?
Electric potential.
What is the unit used to measure electric potential?
volt (V)
What is The Function of Meter?
it is use to measure electric potential (voltage).
What is the function of potentio meter?
it is use to measure electric potential (voltage).
What Is the unit of measure of electric potential in the circuit?
The volt (symbol: V).
What is a unit to measure electric potential?
Volt. As in "the voltage is 2 volts"
What kind of difference is measured in volts?
Volts are a measure of electric potential difference.
What is the voltage between point p and the battery?
The voltage between point p and the battery is not able to measured exactly. You can never measure the absolute electric potential at any point. its just not possible. That is why we talk about difference in potential.
How can you measure electric potential and electric current?

How do you connect a voltmeter to a battery?
To measure the total emf simply connect the battery and voltmeter with the right terminals , but to measure the terminal potential difference which is less than the emf the voltmeter is connected in parallel with the battery
Uses of voltmeter?
A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..
How do you measure electric potential?
A voltmeter is an instrument used to measure electric potential difference. The voltmeter have two electrodes, reference electrode and test electrode, the electrodes are put in two different places where you want to find the potential difference. For instance, if the test electrode is placed on the positive pole and the reference electrode on the negative pole of a 3V battery, the voltmeter would read '+3 volts'.
