Question { Tata Steel Limited, 2341 }

if a 2 ohm resistor,2 ohm capacitor and a 2 ohm inductor is connected parallely to 12v source.Then what is the value of current in each branch.Is current flows in each branch at the same time?If not so then provide the proper sequence


Answer

The inductor will be short circuit the circuit so the inductor placed series to the supply,then the current flow in capacitor is ZERO(its act as a normally open switch)according to oh law the current flow in both inductor and resistor is 6V (I=V/R)
