4. 3. V₁ = VV + V Assume you needed to pass high frequencies through an RC filter but block low frequencies. From the data in Plot 25-1, should you connect the output across the capacitor or across the resistor? Explain your answer. w3 (w=2πf) (a) What happens to the total impedance of a series RC circuit as the frequency is increased? (R+ JNC) 52 z=R- From the above equation the valve of total Impedance of a Series RC Circuit decreases as as frequency is increased Explain why the phase angle between the generator voltage and the resistor voltage decreases as the frequency is increased: VR: IR, VC = 1.ZC, V₁ = XcL-900, xc" //we I= V2+wc (b) = 9 V VR VC I v=Va²+V² 0 R-3/wc) == V (R² +//w²²) Fan (WCR) = VR = V- - R√(R++\/w² (2) - 50 as frequency increases (w=2114), the phase ( A student accidentally used a capacitor that was ten times larger than required in the experiment. Predict what happens to the frequency response shown in Plot 25-1 with the larger capacitor. 5. Assume no current flowed in the series RC circuit because of an open circuit. How could you quickly determine if the resistor or the capacitor were open? There is no voltage drop, so we can't apply KVL. IF Vc = Vm then TS open circuit & resistor is short circuit. It VR = Vc then the open circuit and Capacitor is short circuit 1 radiot the frequency at which the phase shift is 45°.
