Answer / shubham

any element(passive) that stores energy, both inductor and
capacitor stores energy one in form of MF and other in form
of EF. so both can dissipate power when source is removed
but the circuit shall remain connected

Answer / vivek kumar

Inductor stores energy by virtue of magnetic field around
it.So wheh it is disconnected from the source then due to
(e=-Ldi/dt) power is dissipated.

( Re: WHAT SHOULD BE THE RATING OF MCCB FOR 415V,3Ph,50KVAR CAPACITOR BANK Answer # 1 The capacitor current would be kvar x 1000 / (415 x sqrt3). This would be 70a approx. The MCCB selected should have *atleast 1.4 times this current i.e. 1.4 x 70= 98. So you should choose at least 100 A mccb.) regarding to this answer,i would like to know why the current have to times 1.4 to get the right amphere for the mccb.hows the formula to get the 1.4??tq

A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
