7. A two-branch parallel circuit, with Z₁ = 10/0° ohms and Z₂ = 8.0/-30° ohms, has a total current i(t) = 7.07 cos(wt -90°) A. Obtain the complete power triangle. P, Q, p.f. Ohms. 8. A two-branch parallel circuit has branch impedances Z₁ = 2.0-j5.0 ohms and Z₂ = 1.0+ j1.0 ohms. Obtain the complete power triangle for the circuit if the 2.00hm resistor consumes 20W. P, Q, p.f. 9. A two-branch parallel circuit, with impedances Z₁ = 4.0/-30° and Z₂ = 5.0/60° ohms, has an applied effective voltage of 20 V. Obtain the power triangles for the branches and combine them to obtain the total power triangle.
