Question

Consider an uncharged capacitor, inductor, and DC battery in a simple loop circuit. Before t = 0 there is no current flow and the battery is turned on and the circuit is open. At t=0 the circuit is closed. Let T be the period of the resulting oscillations. What will the curcuit be doing at t = T/4? a.capacitor is half charged and current maximal b. capacitor is discharged and current maximal c. capacitor is fully charged and current is zero d. capacitor is discharged and no current e. capacitor is half charged and current is half strength

Explanation / Answer

Since , q = A*sin( t / T ) i =( A / T )* cos ( t / T ) at t = T /4 , e. capacitor is half charged and current is half strength is correct
