A transresistance amplifier receives an input current of 5 mA with a transresistance of 15 kΩ. Calculate the output voltage. Now, if a load of 500 Ω is connected, how does this affect the output voltage?
💡 Hint: Consider the voltage divider formation with the load.
A measuring instrument uses a transresistance amplifier. If its transresistance is set at 12 kΩ and reads an output of 60 V with no load, deduce the input current. What would be the new output if a load of 2 kΩ is connected?
💡 Hint: Reassess the voltage with the impact of load resistance.
