Task id13607
Show that in the circuit of the previous problem (In a circuit consisting of series-connected resistance R, inductance L and capacitance C, a source of sinusoidal EMF of constant amplitude and tunable frequency is connected in series. By changing the frequency of the source, it is tuned into resonance with the frequency of the circuit, then the capacitance is reduced circuit twice and again achieve resonance. Will the current strength change during resonance? What is the ratio of the resonant frequencies corresponding to the first and second cases?) a
