\( PF = \cos \varphi \)
\[ \boxed { \varphi = \cos^{-1}(\mathrm{PF}) } \]where PF = power factor, \( \varphi \) = phase angle
Reactive power:
\[ \boxed { Q = P \cdot \tan(\varphi) } \]\( Q_i = P \cdot \tan(\varphi_i) \)
\( Q_t = P \cdot \tan(\varphi_t) \)
Capacitor rating:
\[ \boxed { Q_c = Q_i - Q_t } \]
