What is coulomb per meter? A unit of electric charge density used to express a number of lines of electric force emanated or absorbed by an electric charge equal to one coulomb per unit area equal to one square meter. (
How does a Coulomb meter work?
The Coulomb meter consists of a capacitor (C) with a voltmeter across it. When the rod A is brought near plate B, the negative charged rod A will attract an equal positive charge to plate B. Capacitor C is now charged, and the voltmeter can measure a voltage across it, proportional to the measured charge.
What is Coulomb's measured in?
Charge is measured in coulombs (C). Since electrons are so small and one electron will not have much of an effect anywhere, it is more useful to refer to packages of electrons. One coulomb of charge is a package equivalent to 6,250,000,000,000,000,000 electrons.

What is coulomb times Volt?
ampere. One joule can also be defined as the following: The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one coulomb-volt (C⋅V). This relationship can be used to define the volt.

One Volt is defined as energy consumption of one joule per electric charge of one coulomb.
What is Joules divided by Coulombs?
Joule is a unit for work done and coulomb is the unit for the charge. The potential is defined as the ratio of the work done to the charge and the unit of the potential difference is volt. Hence, one joule per coulomb is equal to the unit of the potential difference. Therefore it will be equal to one Volt.
