#### Working principles of inductors and capacitors | Electronics360

Inductors and capacitors both store energy, but in different ways and with different properties. The inductor uses a magnetic field to store energy. When current flows through an inductor, a magnetic field builds up around it, and energy is stored in this field. The energy is released when the magnetic field collapses, inducing a voltage in the ...
