Question
For the following RC circuit,where the output voltage is taken across the resistor Explain what the output voltage will be in terms of Vs as w rightarrow 0 and w rightarrow infinity. From this state whether this is a higher or low pass filter. For a straight stick half submerge in water draw at least two rays of light and use then to show what the stick would look like to an observer in the air. without reference to the Doppler shift formula, explain physically why the frequency is lower for a source moving away from a stationary observer.Explanation / Answer
a) when 'w' tends to 0 , the capacitor provides infinite resistance to the current . and hence no current flows. so Vout =0
when 'w' tends to infinity , the capacitor provides 0 resistance to the current . and hence maximum current flows in the circuit such that Vout = Vs
high pass filter
