மின்னழுத்தத்திற்கும் மின்னோட்டத்திற்கும் இடையிலான கோணத்தின் கொசைன் என மின் காரணி வரையறுக்கப்படுகிறது.
ஆற்றல் காரணி = cosϕ
ஆற்றல் காரணி செயலில் மற்றும் வெளிப்படையான சக்தியின் விகிதமாகவும் வரையறுக்கப்படுகிறது.
\(cos \space ϕ={P\over S}\)
விளக்கம்
ஒரு DC சுற்றுக்கு, மின்னழுத்தமும் மின்னோட்டமும் ஒரே கட்டத்தில் இருக்கும், எனவே அவற்றுக்கிடையேயான கோணம் பூஜ்ஜியமாகும்.
ஆற்றல் காரணி = cos ϕ
cos ϕ = cos 0° = 1
cos ϕ = ஒற்றுமை
