Explain how the voltage across the capacitor is change with increasing frequency. Make sure to explain this relative to frequency dependent resistance – the impedance?
Homework Answers
Voltage across a capacitance is inversely proportional to frequency as capacitive reactance is inverse proportional to frequency. Hence with increasing frequency, voltage across capacitor decreases and shows hyperbolic graph.
Resistance is constant wrt frequency. Hence with increasing frequency, voltage across resistance is unchanged.
