Challenge Problems
Push your limits with advanced challenges
Given a voltage amplifier with a gain of 10 and an input voltage of 0.5V, what is the output voltage when connected to a load that causes a 20% drop in the signal due to loading effects?
💡 Hint: First calculate the ideal output, then adjust for loading.
If you cascade two voltage amplifiers where the first has a gain of 5 and the second a gain of 3, what is the total gain considering an output load that reduces the final output voltage by 15%?
💡 Hint: Remember to calculate the overall gain first before applying the loading effect.
