Capacitive Circuit (C-Circuit)
Category : JEE Main & Advanced
(1) Current : \[i={{i}_{0}}\sin \,\left( \omega \,t+\frac{\pi }{2} \right)\]
(2) Peak current : \[{{i}_{0}}=\frac{{{V}_{0}}}{{{X}_{C}}}={{V}_{0}}\omega \,C={{V}_{0}}(2\pi \nu \,C)\]
(3) Phase difference between voltage and current : \[\phi ={{90}^{o}}\](or \[-\frac{\pi }{2})\]
(4) Power factor : \[\cos \varphi =0\]
(5) Power : P = 0.
(6) Time difference : \[\text{TD}=\frac{T}{\text{4}}\]
(7) Phasor diagram : Current leads the voltage by \[\pi /2\]
