Direction: Q.1 to Q.5 |
Let a source of alternating e.m.f. \[E={{E}_{0}}\sin \omega t\] be connected to a capacitor of capacitance C. If I' is the instantaneous value of current in the circuit as instant t, then \[I=\frac{{{E}_{0}}}{1/\omega C}\sin \left( \omega t+\frac{\pi }{2} \right)\]. The capacitive reactance limits the amplitude of current in a purely capacitive circuit and it is given by \[{{X}_{C}}=\frac{1}{\omega C}\]. |
