Question

At mid frequencies capacitve elements ________

primarily affects low frequency response

primarily affects low frequency response

affects both low and high frequency response

are ignored

Answer 1

Capacitive reactance is given by

$X_c=\frac{1}{\omega C}$

It can be seen that capacitive reactance in inversely proportional to frequency. At low frequencies capacitive reactance is very high and hence it acts as open circuit and overall circuit becomes resistive.

At high frequency capacitive reactance is very low and capacitive reactance acts as short circuit. Hence capacitive elements can be ignored at mid frequencies.

Option d is correct
