Pave = Pmaks/2

= V.I.cos θ/2

= [Vm.cos(ωt+θ1)] x [Im.cos(ωt+θ2)]

= Vm.Im.cosA.cosB

A = ωt+θ1

B = ωt+θ2

cosA.cosB = 0,5[cos(A-B) + cos(A+B)]

= 0,5[cos(θ1 – θ2) + cos(2ωt + θ1 + θ2)]

~> P = 0,5Vm.Im[cos(θ1 – θ2) + cos(2ωt + θ1 + θ2)] ✓

~> Q = V.I.sin φ

= √S² – P²

S ~ daya semu

P ~ daya aktif

cos φ ~ faktor daya

sin φ ~ faktor reaktif

~> V(t) = 100√2.cos (ωt+45°) V

I(t) = 2√2.cos (ωt – 30°) A

Pave = 0,5.200.2[cos(75°) + cos(2ωt + 15°)]

= 200[cos(75°) + cos(2ωt + 15°)] W ✓✓

ω ~ kecepatan sudut (rad/s)

cos φ = P/S

= 1 ✓✓
