Hi, I was assigned a lab that requires me to build the attached circuit and show how the output signal is the integral of the input signal. Basically I can't understand what the function of the 10MOhm feedback resistor is. Its giving me a headache when I try to derive my proof for the...

I'm having difficulties understanding the concept of power and how you generate it in a circuit. Mainly I'm uncertain about how electrical energy can be used to produce power and what are the conditions for producing it (are resistors required?) Would someone be so kinda as to give me an anaolgy...
