Will the value of the energy of a charged capacitor change if we take a current source with a higher EMF? If you change, how?
| December 29, 2020 | education
The energy of a charged capacitor changes, since work is done when electric charges move and the potential difference across the capacitor changes from its initial value to zero. A charged capacitor has energy:
E = Uq / 2.
The charge is determined by the formula: q = CU.
Substituting the charge formula into the energy formula, we get the formula to answer the question:
E = CU ^ 2/2.
The mathematical formula Y = aX ^ 2 is a parabola.
Answer: The energy of a capacitor changes in a parabolic relationship.
