Use the node-voltage method to find the steady-state expression for vo(t) in the circuit in (Figure 1) if vg1= 18 sin(400t+143.13∘)V, vg2= 18.03cos(400t+33.69∘)V. Write the steady-state expression for vo(t) as vo=Vocos(ωt+ϕ), where −180∘<ϕ≤180∘.
Find the numerical value of Vo.
Find the numerical value of ϕ.
