Use the node voltage method to find the steady-state expression for io in the circuit seen in (Figure 1) if ig = 4 cos2500 t A and Vg = 24 cos(2500 t +90?)V . Write the steady-state expression for io ( t ) as io = Io cos(omega t + phi ), where ?180?phi ?180?.

Find the numerical value of Io . and phi
