• Both capacitors and inductors are energy storage devices • They do not dissipate energy like a resistor, but store and return it to the circuit depending on applied currents and voltages • In
Thus, the power delivered to the inductor p = v *i is also zero, which means that the rate of energy storage is zero as well. Therefore, the energy is only stored inside the inductor before its current reaches its maximum steady-state value, Im. After the current becomes constant, the energy within the magnetic becomes constant as well.
Some common hazards related to the energy stored in inductors are as follows: When an inductive circuit is completed, the inductor begins storing energy in its magnetic fields. When the same circuit is broken, the energy in the magnetic field is quickly reconverted into electrical energy.

While one inductor's current is increasing, the other's is decreasing. There is also a significant reduction in the required inductor energy storage (approximately 75%). The inductor's volume, and therefore cost, are reduced as well. See Linear Technology's Application Note 77 for complete details.
In such cases, the current, I, flowing through the inductor keeps rising linearly, as shown in Figure 1 (b). Also, the voltage source supplies the ideal inductor with electrical energy at the rate of p = E *I. Without the internal resistance, the inductor is lossless because it cannot produce heat or light from the available energy.
