A current source of i(t) =2cos(100t+90º ) A is connected in parallel with a resistor of R Ω, a capacitor of C μF, and an inductor of L mH. (In other words, all four elements are in parallel.)

Determine the phasor voltage V across the current source, assuming the sign of the voltage is positive. If V = A + jB, what is the real part A? (Do not give a unit in your answer.)

(Assume R = 60, L=550, and C=40.)
