Given an amplifier with a voltage gain of 100, applying feedback reduces this by desensitization factor 5. Calculate the new voltage gain.
💡 Hint: Simplify the gain according to the factor.
You have a circuit where the input resistance increased from 1kΩ to 5kΩ after feedback. What does this indicate about the circuit?
💡 Hint: Consider the implications for the amplifier's performance with loading.
