Challenge Problems
Push your limits with challenges.
Question 1
You have a voltage amplifier where the input voltage is 2V, and the gain is 15. Calculate the output voltage. Then, if you add a load of 500Ξ© at the output and the amplifier has an output resistance of 100Ξ©, determine how this affects the output voltage observed on the load.
π‘ Hint: Assume the load takes away a portion of the voltage; use the voltage divider rule.
Question 2
If the input resistance of the amplifier is 1000Ξ© and the source resistance is 200Ξ©, what is the effective input voltage supplied to the amplifier?
π‘ Hint: Remember how resistances in series in the input divide the voltage.
