Applying KVL in op amp with floating source
From my understanding, the solution first applies the summing point constraint even though there is no ground on the non-inverting input, leading to 0V on both inputs. But how do they apply KVL acros …

Is it correct to apply KVL through the 2 inputs of an op amp?
The question asks; "P14.25 Analyze each of the ideal-op-amp circuits shown in Figure P14.25 to find expressions for 𝑖𝑜. The top part is the question, the bottom is the solution from the solutions ma …

Infinite output impedance in amplifier, instead of 0?
The question asks: "Exercise 14.5 Assume an ideal op amp and use the summing-point constraint to find an expression for the output current io in the circuit of Figure 14.14. Also find the input and …
