Ohm's law applies to the entire circuit. This site will not work properly because your browser does not support JavaScript! The right graph shows the impedance and the phase angle of a series RLC circuit against frequency. Like a pure series LC circuit , the RLC circuit can resonate at its resonant frequency and the resistor increases the decay of the oscillations at this frequency. Radio-frequency engineering RF engineering is a field of engineering that deals with devices that transmit or receive radio waves in the radio frequency spectrum 3 kHz to GHz.
