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..
What is meant by 1 Joule work?
One joule of work is done on an object when a force of one newton is applied over a distance of one meter. The joule is named after James Prescott Joule who lived from 1818 until 1889.
What is 1 Joule equal to in Newton Metres?
One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.

What do you mean by 1 Joule?
joule. [ jōōl, joul ] The SI derived unit used to measure energy or work. One joule is equal to the energy used to accelerate a body with a mass of one kilogram using one newton of force over a distance of one meter. One joule is also equivalent to one watt-second.
How do you calculate voltage charge?
You can also use Ohm’s law (V = IR) to calculate current from voltage and resistance. For a circuit with voltage 3 V and resistance 5 Ω that is applied for 10 seconds, the corresponding current that results is I = V / R = 3 V / 5 Ω = 0.6 A, and the total charge would be Q = It = 0.6 A × 10 s = 6 C.
How many joules are in a lightning strike?
1 million joulesThe average lightning strike contains about 1 million joules, enough energy to fry the founding father in his boots. “The typical house in the U.S. has 100 amp service or about 28 horsepower,” says Kirtley.
How many volts is 360 joules?
Defibrillators need clear, reliable power that rapidly accumulates in capacitors. This can be between 200 volts and 100 volts, at 360 joules, and 45 amps. The shock lasts for nearly about 45 seconds. After that, the capacitors needed to be freshly charged.
What is the formula for 1 Joule?
The definition of the joule as J=kg⋅m2⋅s−2 has remained unchanged since 1946, but the joule as a derived unit has inherited changes in the definitions of the second (in 1960 and 1967), the metre (in 1983) and the kilogram (in 2019).
How many volts are in a Watt?
Convert the wattage of 1000 watts into volts for a circuit that has an amperage of 10 amperes. Using the power equation of 1 watt = 1 ampere × 1 volt and translating that formula to find volts, you end up with 1 volt = 1 watt ÷ 1 ampere. Divide 1000 watts by 10 amperes and the resultant voltage would equal 100 volts.
How do you calculate charge from Joules and voltage?
The equation is: energy transformed (joule, J) = potential difference (volt, V) × charge (coulomb, C). For example, if the potential difference is 100 V and the charge is 3 C, the calculation is 100 × 3.
How many joules is dangerous?
Remember: Greater than 10 Joules is considered hazardous. Greater than 50 Joules is a lethal level. Relatively small capacitors can store potentially lethal charges.
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.
What is the difference between a charge and a current?
The main difference between current and charge: Current: It is the rate of flow of charge (generally electrons). Current (I) is the physical quantity measured in amperes (A). … Charge (Q) is the physical property of matter measured in Coulombs (C).
What does 200 joules mean?
Energy absorption/dissipation – This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more.
