AC परिपथ में शक्ति

AC परिपथ में शक्ति औसत और अभिक्रियाशील शक्ति का संयोजन होती है।

औसत और अभिक्रियाशील शक्ति का फेजर योग आभासी शक्ति देता है।

S = P + jQ

जहाँ, S = आभासी शक्ति

P = औसत शक्ति

Q = अभिक्रियाशील शक्ति

आभासी शक्ति इस प्रकार दी जाती है:

S = Vrms x Irms

औसत या सक्रिय शक्ति इस प्रकार दी जाती है:

P = S cos ϕ

P = Vrms x Irms cos θ

 प्रतिक्रियाशील  शक्ति इस प्रकार दी जाती है:

Q = S sin ϕ

Q = Vrms x Irms sin θ
