Explanation: In op-amps a number of transistors, resistors and capacitors are integrated on the same substrate. In fact substrates act as an insulator and separate these components. So, the various components are connected by conducting paths. However, when two conducting paths are separated by an insulator, it acts as a capacitor (stray capacitor). 6.
