सक्रिय शक्ति निम्न द्वारा दी जाती है:
\(P=VIcos(\theta_v-\theta_i)\)
प्रतिघाती शक्ति निम्न द्वारा दी जाती है::
\(Q=VIsin(\theta_v-\theta_i)\)
आभासी शक्ति निम्न द्वारा दी गई है:
\(S=\sqrt{P^2+Q^2}\)
गणना
दिया गया है, V = (100 + j10) V = 100.49∠5.71°
I = (20 − j10) A = 22.36∠-26.56°
\(P=100.49\times22.36 \times cos(5.71-(-26.56))\)
P = 1900 W
