In this lesson, you will learn how to solve op-amp circuit problems that have two op-amp. The Op-Amps are ideal.
The best way to solve op amp question is to use nodal analysis. Pick any node and consider all the currents are either incoming or outgoing. then add the voltage difference between two node divided by resistance between these two nodes.
Consider the circuit at the input of an op amp. The current flowing toward the input pin is equal to the current flowing away from the pin (since no current flows into the pin due to its infinite input impedance). The same cannot be said for the output, since the op amp can source or sink current.
