In the circuit shown in the figure, one of the three switches is kept closed and other two are open. The value of resistance is R = 20 `Omega`. When the angular frequency(w) of the 100 V source is adjusted to 500 rad/s, 1000 rad/s and 2000 rad/s it was found that the current I was 4A, 5A and 4A respectively.
(a) Which switch id closed ?`(S_(1),S_(2) "or" S_(3))`
(b)Find the value of L and C.
