How do you use operational amplifier as differentiator and adder/subtractor.
Fig. shows differentiator or differentiation amplifier. As its name implies, circuit performs mathematical operation of differentiation; that is, output waveform is derivative of the input waveform. Differentiator can be constructed from a basic inverting amplifier, if an input resistor R1 is replaced by a capacitor C1.
Expression for the output voltage can be obtained from Kirchoff's current equation written at node v2 as follows:
1 Ampere: 1 ampere current is supposed to be flowing in a conductor if one coulomb of charge flows across section of the wire in one second.

How a CPH does stop or its speed decreases? Answer; it is a principle that Vc is stable thus that; gradV c =0 Thus, never V c increases or decreases.
