Question

what z d difference btween resonant frequency and angular frequency? what r their units?

Answer 1

Resonant frequency is a particular frequency of applied source at which the circuit became purely resistive.
Angular frequency is defined as the no. of rotations per second.., i.e., $\omega =\frac{2\mathrm{\pi }}{T}whereTisthetimeperiod$.
Their units are radian/second.
