| Q. |
In an RC coupled CE amplifier, when the input frequency increases, which of these are incorrect? |
| A. | reactance csh decreases |
| B. | voltage gain increases |
| C. | voltage gain decreases due to shunt capacitance |
| D. | an rc coupled amplifier behaves like a low pass filter |
| Answer» B. voltage gain increases | |
| Explanation: when frequency increases, shunt reactance decreases. the voltage drop across shunt capacitance decreases and net voltage gain decrease. rc coupled amplifier acts as a low pass filter at high frequencies. | |
