Joules are a measure of electrical energy and coulombs are a measure of charge. These measurements can be used to derive the voltage using this formula. Thus, the voltage is equal to the energy in joules divided by the charge in coulombs. For example, let’s convert 20 joules and 5 coulombs to volts.
Similarly, Are joules the same as volts? A volt is a unit of measure assigned to the electrical potential or voltage across a conductor. … However a joule is a unit of energy or work done, to move an electric charge through an electric potential.
How do you find the joules? In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.
How do you convert nC to C? 1 nC = 1 * 10–9 C.
Secondly How do you find joules from voltage and current? Volts, amps and joules
- The voltage between two points on a circuit is called the potential difference between those two points.
- Current is the rate of flow of charge through a wire. …
- Energy = joules = volts x charge = voltage x current x time. …

Volt Ampere to Joule/second Conversion Table.
Volt Ampere [V*A] | Joule/second [J/s] |
---|---|
0.01 V*A | 0.01 J/s |
0.1 V*A | 0.1 J/s |
1 V*A | 1 J/s |
2 V*A | 2 J/s |
How do you find joules from amps and volts? If voltage, (V) equals Joules per Coulombs (V = J/C) and Amperes (I) equals charge (coulombs) per second (A = Q/t), then we can define electrical power (P) as being the totality of these two quantities. This is because electrical power can also equal voltage times amperes, that is: P = V*I.
How do you calculate kJ?
kJ is the units “Joules” multiplied by a number (kilo = x1000) that has no units of it’s own. kJ/mol is just the J multiplied by a number that has no units on it’s own: 1000/mol.
How do you convert J to kJ? To convert a joule measurement to a kilojoule measurement, divide the energy by the conversion ratio. The energy in kilojoules is equal to the joules divided by 1,000.
How many C is nC?
Nanocoulomb to coulombs conversion table
Charge (nanocoulomb) | Charge (coulomb) |
---|---|
0 nC | 0 C |
1 nC | 10 – 9 C |
10 nC | 10 – 8 C |
100 nC | 10 – 7 C |
What is nC in electric field? The SI units of electric field are newtons per coulomb, or N C–1.
What is nC m?
The symbol of Nanocoulomb/Meter is nC/m. This means you can also write one Nanocoulomb/Meter as 1 nC/m.
What is joule formula?
In equation form: work (joules) = force (newtons) x distance (meters), … One joule is defined as the amount of work done when a force of one newton is exerted through a distance of one meter.
How many joules are in a Watt? Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.
How do you calculate battery joules? For any voltage, mAh X voltage x 3.6 = Joules of energy.
For example. A 7.2 Volt battery that delivers 100 mAh of charge has delivered, 100 x 7.2 x 3.6 = 2592 Joules of energy.
How do you calculate joules?
In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph. In practical terms, even a small force can do a lot of work if it is exerted over a long distance.
How do you convert joules to Watts? Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.
Are amps and joules the same?
While joules could be converted to watts, amps cannot be converted to joules as they two vary in many respects as the units of measurement. An amp measures the power, a joule is used to measure the total work done. The symbol of an Amp is ‘A’ and the symbol of a joule is ‘J’.
How many joules are in a amp? One joule is the work needed to move one ampere through one ohm of resistance for one second.
How do you calculate joules in water?
Example: If 10 kilograms of water are heated from 10 degrees Celsius to 50 degrees Celsius, how much energy (in joules) did they absorb? Answer: The specific heat capacity of water is (roughly) 4.184 kilojoules / kg K. (10 kg) × (40 degrees Celsius temperature change) × (4.184 kJ / kg K) = 1673.6 kilojoules.
How do you convert joules to kilo joules per mole? The prefix “kilo” means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence “per mole”. To get the energy for one molecule, divide kJ/mol by Avogadro’s number, 6.022 x 1023.
How do you find joules from Watts and time?
Power in general is defined as energy over time. Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running.
