In the circuit shown, find the value of the reactance X so that the circuit is purely resistive, i.e., the impedance seen by the source is real. Find the steady-state current i(t) associated with the phasor current I for this value of X, if the angular frequency of the voltage source is ? = 1, 000 rad/sec.
