Answer:
power = 384.92 W
Explanation:
given data
resistance = 44.0 Ω
impedance = 71 Ω
ΔVrms = 210 V
to find out
average power
solution
we know here power formula that is
power = [tex]\frac{V^2rms}{impedance}[/tex]cos∅ .........1
we know here cos∅ = [tex]\frac{resistance}{impedance}[/tex]
cos ∅ = [tex]\frac{44}{71}[/tex] = 0.6197
so from equation 1
power = [tex]\frac{210^2}{71}[/tex] × 0.6197
power = 384.92 W
