why is the qestion not answered yet

want the qesution answered in that format

(LED-GREEN, ACTIVE Use an oscilloscope to compare the voltages at: non-inverting input of the amplifier / signal generator output output of the amplifier, driving the LEDs Use current probes or ammeters to monitor: current at positive supply of the amplifier current at non-inverting input of the amplifier / signal generator output current at output of the amplifier, driving the LEDS Does the output voltage of the amplifier follow the input voltage? Where is the current powering the LEDs sourced from? Are the LEDs loading the signal generator? Could a buifer amplifier be used to improve the circuit from Exercise 17 Why are there. no resistors in series with the LEDs? Document and discuss your approach. Aims and Objectives
