Question

The capacitor in the figure below is designed to filter low-frequency signals, impeding their transmission between circuits. Circuit Circuit Signal (a) What capacitance is needed to produce a 122 k2 reactance at a frequency of 204 Hz? 6.31 nF (b) What would its reactance be at 1.00 MHz? 25.2 (c) What are the implications of your answers to (a) and (b)? (Select all that apply.) O High frequencies transmit better than low ones. The capacitor does not do what it is designed to do. Reactance is larger at high frequencies Reactance is smaller at high frequencies. The capacitor does what it is designed to do. Low frequencies transmit better than high ones.

Explanation / Answer

c). As from above parts we can see that Capacitor provides high reactance/ resistance to low frequency and low reactance/resistance to high frequency. Hence it acts as High frequency filter that means high frequencies transmits better than low ones.

(i). The capacitor does what it is designed to do: Its not the fact as it transmits high frequencied better than lower ones.

(ii). High Frequency tansmit better than low ones: Its True

(iii). Low Frequency transmit better than high ones: Its false as said above

(iv). Reactance is smaller at high frequencies: Its true as shown by part (b)

  (v). The capacitor doesnot do what it is designed to do: Its True since it acts as a high pass filter

(vi). Reactance is larger at high frequencies: Its False as shown in above parts.
