Topic: Electronics Engineering
The approximate frequency of oscillation of the circuit shown below is
- A. 8.3 kHz
- B. 16.6 kHz
- C. 7.2 kHz
- D. 3.6 kHz
Answer: C. 7.2 kHz
Explanation: This is an astable multivibrator. So, the frequency $= \frac{1}{1.38~RC} = \frac{1}{1.38\times10\times10^{3}\times0.01\times10^{-6}} = 7.246~kHz$
