Challenge Problems
Push your limits with advanced challenges
You have a feedback system with an input resistance of 10Ω and a feedback factor β of 0.1. If the output resistance changes from 5Ω to 10Ω, how would the supplied current change?
💡 Hint: Use the relationship between voltage, current, and resistance to assess changes.
If you were to incorporate a new parallel resistor of 4Ω in a feedback loop where the initial input resistance is 12Ω, what would be the new input resistance?
💡 Hint: Remember to compute the equivalent resistance first before determining the new input value.
