Question

An inductor 20 _ 10ذ3 henry, a capacitor 100_F and a resistor 50½ are connected in series across a source of EMF V = 10 sin 314t. If resistance is removed from the circuit and the value of inductance is doubled, then the variation of current with time in the new circuit is ذ

Answer

None of these

0.52 cos 314 t

0.52 sin 314 t

0.52 sin (314 t + π/3)
