1. The problem statement, all variables and given/known data Two serially connected impedances one with [itex]\Phi[/itex] = π/3 and other with [itex]\Phi[/itex] = 0. They have apparent power of S1=S2=200VA. Find total apparent power. 2. Relevant equations S = sqrt(P^2 + Q^2) 3. The attempt at a solution so cosPhi = P1/S1. So P1=cosπ/3*200=100W. For other one P2 = cos0*200=200W. How should I continue? Should I find Q too and derive somehow a equation to sum those powers?
