where coil store energy?? dear all well many times when we speaks about coils , they say that coil store energy like cap. stors charges on its plates , the coil store the magentic energy inside its core so in case of air coil where the energy is stored ! thanks all bye

umm we never anyone of US while studying charging & discarging of Cap we study radiated and if so , you mean that the connecting wires are antennas but our problem is valid whatever was the wire length (so short , so long ...etc) so the raditation depends a lot on the antenna length ?

Where is has the other half of the energy gone ?? this is quite a common question asked in many interviews.There are two capacitors C.Intially one capacitor is charged to V volts while the other is at zero volts.At t=0,a switch connects both of them in parallel.Due to charge sharing the voltage...
