Please provide values below to convert joule/second [J/s] to volt ampere [V*A], or vice versa.

Joule/second to Volt Ampere Conversion Table.
Joule/second [J/s] Volt Ampere [V*A]
0.1 J/s 0.1 V*A
1 J/s 1 V*A
2 J/s 2 V*A
3 J/s 3 V*A

Herein, how many amps are in a Joule?

100 x 7.2 x 3.6 = 2592 Joules of energy. As we saw above, since a mAh is 1/1000 of an Ah, to convert Ah (amp hours) to Joules just use 1000 x 3.6 = 3600 as the conversion factor instead of 3.6.

One may also ask, are Joules and amps the same? These are units for different things. Amps (amperes) are a unit of current which is the rate at which charge flows. Joules are a unit of work or energy. Watts are a unit of power which is the rate at which energy is generated or consumed.

In this way, how do joules relate to amps?

So to work out the total rate of energy conversion in a circuit or appliance you have to multiply Amps drawn by Volts supplied. In fact these units are designed so that Amps times Volts gives you exactly the number of Joules per second being converted.

How many amps is 360 joules?

16 Amps

### How much is a joule of electricity?

Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds. In electrical terms, the joule equals one watt-second—i.e., the energy released in one second by a current of one ampere through a resistance of one ohm.

### How many joules are dangerous?

Greater than 10 Joules is considered hazardous. Greater than 50 Joules is a lethal level.

### What is the voltage in a Joule?

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.

### How do you convert volts to mAh?

Convert mAh (milliamphours) to time in hours
If instead of the current you have voltage and watts, then the formula is (mAh*Volts)/(Watts*1000) = (hours). For example, if you have a 3000 mAh battery that runs at 5 Volts and 15 Watts, then the time that the battery will last for is (3000*5)/(15*1000) = 1 Hours.

### How many joules is 100 watts?

Answer and Explanation: A 100-watt light bulb uses 100 joules of energy per second, by definition of a watt.

### How do you calculate joules?

Multiply watts by seconds to get joules.
A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you'll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.

### How many amps is a Coulomb?

The answer is 1. We assume you are converting between ampere and coulomb/second. You can view more details on each measurement unit: amps or coulombs per second The SI base unit for electric current is the ampere. 1 ampere is equal to 1 amps, or 1 coulombs per second.

### What does joules 3s mean?

"Joules 3s" represents the actual amount of power delivered in 3 seconds. Beware of jump starters just claiming high amperage ratings, as amps without time and voltage mean absolutely nothing. The average vehicle jump starts in 1-3 seconds, making peak amps somewhat worthless.

### What are the units for joules?

The joule (symbol J) is the SI unit of energy—a measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). Therefore, one joule equals one newton•meter.

### What is amp power?

With electricity, we measure the amount of charge flowing through the circuit over a period of time. Current is measured in Amperes (usually just referred to as "Amps"). An ampere is defined as 6.241*10^18 electrons (1 Coulomb) per second passing through a point in a circuit.

### How many joules does a AA battery have?

A Manganese/Alkaline AA cell it rated at about 2.4 amp-hours. If we assume 1.5 volts average this gives approximately 3.6 watt-hours (slightly optimistic). Since there are 3,600 seconds in an hour this is equivalent to 12,960 Joules.

### How do you convert coulombs to amps?

The equation is:
1. charge (coulomb, C) = current (ampere, A) × time (second, s).
2. energy transformed (joule, J) = potential difference (volt, V) × charge (coulomb, C).
3. F = kq1q2 ÷ r2.

### What is the difference between Joules and 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. Whereas, voltage is the speed at which the current is moving along the line.

### How many joules does it take to charge a phone?

If I'm getting my physics straight, 1 watt hour is 3,600 joules, and if you assume a rough voltage of 4V, 1 milli-amp hour is 0.001 * 4v * 60 * 60, or 14.4 joules. A typical phone battery might have 2,000 mAh, or about 29,000 joules.

### How many joules are in a Coulomb?

1 coulomb = the amount of electrical charge in 6.24 x 10^18 electrons. Joules = a measure of energy. Voltage is the amount of energy (J) per unit charge (C). 1 volt is exactly 1 joule of energy done by 1 coulomb of charge (1J/C).

### What is the current?

Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current. Electrons, the most common charge carriers, are negatively charged.

### How many joules of electricity can kill you?

This would be 12 Watts for 2 seconds, or 24 Joules of energy. This is still not very much. If the electric shock victim is someone in a weakened condition (and possibly dependent upon a pacemaker), then a much smaller electric shock could be fatal.
