By definition a volt is a joule per coulomb,

V=W/Q (V is voltage, W is work done or energy measured in joules, Q is charge measured in coulombs)

therefore 1 volt is 1 joule per 1 coulomb of charge

(1C of charge is a very large amount to expect to see very small numbers for charge)

No, that is incorrect. Voltage is the electrical potential difference between two points in a circuit, measured in volts. Joules is the unit of energy, and it represents the work done or energy transferred when a force of one newton acts over a distance of one meter. The relationship between voltage and energy per unit charge (joules per coulomb) is given by the equation E = QV, where E is energy (joules), Q is charge (coulombs), and V is voltage (volts).

What is voltage unit?

Voltage is "electrical pressure", so to speak, or energy per charge. Volts is joules per coulomb.


How many joules per coulomb are given to charge flow in a 120-volt circuit?

In a 120-volt circuit, each coulomb of charge flowing receives 120 joules of energy. This is calculated using the formula: energy = voltage x charge. So, 120V x 1C = 120 joules.


How do you calculate how much energy a battery has with only the volts and coulombs?

To calculate the energy stored in a battery with volts and coulombs, you can use the formula: Energy (Joules) = Voltage (Volts) x Charge (Coulombs). Multiply the voltage by the charge of the battery to get the energy capacity in Joules.


How much energy is given to each coloumb of charge passing through 6v battery?

Each Coulomb of charge passing through a 6V battery gains 6 Joules of energy. This can be calculated using the formula Energy = Charge x Voltage. So, for every Coulomb of charge passing through a 6V battery, it receives 6 Joules of energy.


How many volts in 3 joules by one coulub?

3 joules of energy per 1 coulomb is equivalent to 3 volts. This relationship is based on the definition of voltage, which is energy per unit charge.


How much energy given to each coulomb of charge passing through a 6 volt battery?

The potential difference ('voltage') is equal to the work done per unit charge, i.e. the energy given to each Coulomb of charge. So, a six Volt battery provides six Joules of energy to each Coulomb of charge.


What is the amount of energy in an electric charge?

The amount of energy in an electric charge is measured in Joules and is calculated by the formula E = QV, where E is the energy, Q is the charge, and V is the voltage. The energy of a charge is proportional to the amount of charge and the voltage it is subjected to.


What is the voltage at the location of a Coulomb charge that has an electric potential?

The voltage at the location of a Coulomb charge with an electric potential is the work required to move a unit positive charge from a reference point to that location. It is a measure of the potential energy per unit charge at that point in the electric field.


How many joules of energy does each coulomb of charge have at the battery terminals?

Each coulomb of charge has an energy of one joule at the battery terminals. This is because the potential difference between the terminals of a battery is defined as one volt, and one volt is equivalent to one joule of energy per coulomb of charge.


Can you please define current?

Current is the flow of electrical charge, measured in amperes. One ampere is defined as one coulomb per second. One coulomb is about 6.24x1018 protons or electrons.A few more terms to crystallize things... Some people confuse current and voltage. They are not the same thing. Current, as stated above is a flow of charge, while voltage is the energy behind that charge, in volts, or joules per coulomb. Power is the rate of work done by the energy, in joules per second or watts, or volts times amperes. Energy, joules, is the integral of the power.


What is the difference between voltage and power?

Voltage is electromotive force, in joules per coulomb. Power is energy transfer rate in joules per second, also known as watts.Not asked, but answered for completeness sake, and also to show the relationship between voltage and power, current is charge transfer rate in coulombs per second. So, if you multiply voltage (joules per coulomb) by amperes (joules per second) you get watts (joules per second).


For an electric current to flow the only thing needed is for two objects to have a difference in charge?

Actually, they need a difference in energy per charge. Voltage is energy per charge, in joules per coulomb, and a voltage differential is what is required to create an electric current flow.
