The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889). Metric conversions and …
Webb28 jan. 2024 · In other words, it is a measurement of the energy contained within an electric field, or an electric circuit, at a given point. It is equal to the work that would have to be done per unit charge against the electric field to move the charge from one point to another. Voltage is a scalar quantity; it does not have direction. http://physics.bu.edu/~duffy/py105/Energy.html
Webb10 apr. 2024 · Joule and Calorie both are different units of measurement of the same entity, energy, in this case. They differ in their values and due to the fact that while calorie is often used to measure energy; joule is the standard unit (SI unit) for derivation of energy, work and heat. 1 J= 4.184 Cal (where J represents joule; “Cal” refers to calorie)
