Best answer: What is the unit of electric work done convert the unit to Joule?

So if 1 watt = 1 joule per second, it therefore follows that: 1 Joule of energy = 1 watt over one unit of time, that is: Work equals Power multiplied by Time, (V*I*t joules). So electrical energy (the work done) is obtained by multiplying power by the time in seconds that the charge (in the form of a current) flows.

How do you convert units to Joules?

What is electrical work done?

It is the battery which gives the energy to run the electron from negative potential or lower potential to positive potential or high potential. This is known as work done by electron or simply electric work. … Thus we can say, the rate of doing work is called Power.

How do you calculate electrical energy in Joules?

Electric energy = P × t = V × I × t = I2 × R × t = V2t / R.

  1. S.I unit of electric energy is joule (denoted by J), where 1joule = 1watt × 1 second = 1volt × 1ampere × 1second.
  2. Commercial unit of electric energy is kilowatt-hour (kWh), where 1kWh = 1000 Wh = 3.6 ×106J = one unit of electric energy consumed.

What units are in joules?

joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.

How do you convert an answer to 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.

What is the work done formula?

Scientifically Work done formula will be given as, W = F * d: In this case, the force exerting on the block is constant, but the direction of force and direction of displacement influenced by this force is different.

What is the symbol and unit of electric work?

Electrical & electronic units table

Unit Name Unit Symbol Quantity
Ampere (amp) A Electric current (I)
Volt V Voltage (V, E) Electromotive force (E) Potential difference (Δφ)
Ohm Ω Resistance (R)
Watt W Electric power (P)

What is the unit of work done?

One joule is defined as the amount of work done when a force of one newton is exerted through a distance of one meter. In the English system of units, where force is measured in pounds, work is measured in a unit called the foot-pound (usually abbreviated ft-lb).

What is work done equal to?

Work done on a body is equal to the increase in the energy of the body, for work transfers energy to the body. If, however, the applied force is opposite to the motion of the object, the work is considered to be negative, implying that energy is taken from the object.

What is the unit of electric power?

Electricity is measured in units of power called Watts, named to honor James Watt, the inventor of the steam engine. A Watt is the unit of electrical power equal to one ampere under the pressure of one volt.

Is Joule a SI unit?

The SI unit for energy is the joule (J): 1 J=1 newton metre (N m).

How do you find joules in chemistry?

Then, in terms of SI base units a joule is equal to a kilogram times meter squared divided by a second squared (kg×m2s2) ( kg × m 2 s 2 ) . Another common unit of energy that is often used is the calorie (cal), which is equivalent to 4.184 J.
