Final answer:
The statement given is false; the capacitive reactance decreases as the frequency increases, leading to a smaller effect on the overall impedance in an AC circuit.
Step-by-step explanation:
The statement that the magnitude of the impedance of the capacitor will increase if the frequency of the source is increased is false. In an AC circuit, the reactance of a capacitor (Xc) is inversely proportional to the frequency (f) of the voltage source. As the frequency increases, the capacitive reactance decreases. This is because a capacitor passes more current as the frequency of the AC voltage applied to it increases, behaving almost like a short circuit at very high frequencies. This means that at higher frequencies, the capacitor has a smaller effect on the overall impedance of the circuit.
