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.
The exponential characteristics of a practical inductor differ from the linear behavior of ideal inductors; both store energy similarly–by building up their magnetic fields. These magnetic fields have undesirable effects on the inductors and nearby conductors, causing several safety hazards.
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. This electrical energy appears as a high voltage around the circuit breakpoint, causing shock and arcs.
Therefore, considerable mechanical and electrical support should be provided to dissipate any stress or heat produced safely. Another safety consideration is to verify the de-energized state of inductors. Any residual energy in inductors can cause sparks if the leads are abruptly disconnected.
The inductor behaves like a load and stores energy to prevent ripples from producing excess current. It acts like a current supply when the ripple reduces the current value. In each case, the inductor prevents the ripples from influencing the regulated DC.
