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.
a) A uniform mild steel ring has a diameter of 50mm and a cross-sectional area of 1cm 2 . Determine the mmf essential to produce a flux of 50µWb in the ring. (b) I
Capacitors in parallel: Three capacitors are connected in parallel. If on closing the switch S a current I flows in the circuit, then from Kirchoff's first law:
(i) It is the length of single wave. (ii) Wavelength is similar to the distance covered by the wave during the time in which any one particle of the medium done one vibration ab
