Hello, I can`t understand the following: Let`s say that we have a simple capacitor with two plates and air between them. And this capacitor is in a series circuit with a switch, voltage source and a resistor. Also, the capacitor is discharged and the switch is open. The voltage source is...

I would like to ask you what it is meant by "symmetric input" in the instrumentational amplifier schematics and in the differential amplifier? I can`t understand what is the difference between symmetric and non symmetric input and output as parameters. Can anyone explain ? Thanks

Hello, I would like to ask someone to explain me the basic physics of the common emitter configuration. With the common base configuration i am understanding all the processes with holes and electrons in the npn transistor perfectly. In the common emitter configuration i can`t understand...

Dear uart, thank you for your quick and kind reply, now i understood this process, thanks.

Hello, Here is my question: If we have a regular PN junction diode, which is forward biased we will observe the effect "injection", we will have more minority carriers than normal near the PN junction. I would like to ask you whether this "injection" is observed during the whole period...

Thank you for the clarification, it seems reasonable. By the way, does this Coulter Counter has something in common with the Beckam Coulter company ?

The question is related to impedance cell counting, determining cell`s size etc. This method is working like this: "A small portion of the diluted fluid in each bath is allowed to flow past a small aperture. An electrical current is produced in each aperture by two electrodes, one on the...
