(a) For the circuit in Fig. 21.17, what would be the effect on the resonance frequency if one of the capacitors had a capacitance value smaller than that shown: (1) it would decrease, (2) it would increase, or (3) it would remain the same? Explain your reasoning.
(b) Determine the new resonance frequency if one of the capacitors is replaced by one with a capacitance of 1.50 μF.
