Energy of an inductor equation
WebEnergy Stored in Inductor Due to energy conservation, the energy needed to drive the original current must have an outlet. For an inductor, that outlet is the magnetic field—the energy stored by an inductor is equal to the work needed to produce a current through the inductor. The formula for this energy is given as: E = 1 2 LI 2 \text{E} ... WebThe energy stored in the capacitor is given by U E = q 2 / 2 C. Similarly, the energy stored in the inductor is U B = 2 1 L i 2. The rate of energy supply by the driving emf device is P ε = i ε where i = I sin (ω d − ϕ) and ε = ε m sin ω d t. The rate with which energy dissipates in the resistor is P R = i 2 R.
