What are the applications of an Integrator circuit in electronics circuit?

Answer 1

Two very common uses for an integrator are as a filter and for use in a servo control system. Integrators are also used in computer simulators. For example if a signal representing acceleration is fed into an integrator, a signal representing velocity can be obtained.

Using Ohm's law, current is I = E/R. If R is infinite... I will be zero. So by definition, an open circuit means that there is infinite resistance in your current path. That is, there is some point in your loop that is a perfect insulator that opposes all current flow though it. So it's the insulator that "chooses" to allow flow or not, not the electrons. What is an insulator, then? It's a medium whose electrons can't be moved around by electrical pressure (that is, voltage.) Using the water-and-pipe analogy, an insulator is like a valve that is shut off, so it holds pressure (voltage) on either side of it. As a practical matter, real insulators have a breakdown limit which can be overcome if the voltage is high enough (think lightning for example.)

Answer 3

we can use integrator circuits as summing and diffrence applications
