1. ### Understanding the capacitor deeply

yes but first we are discussing the ideal case and second, this does not explain why the impedance drops when freq. arise. electrons do not leave one plate do they!? I think that's the electron gun when electrons actually leave the plate.In capacitor their electrical field as I explained...
2. ### Understanding the capacitor deeply

hello every body, I am trying to understand the capacitor behavior as deeply as i can ...I posted this thread in Classical Physics section but I later think it could be better if I post it here in EE. consider a simple capacitor with two plates A and B ---| |--- 1- why the charge on both...
3. ### Understanding the capacitor deeply

capacitance depends only on geometrical aspects + the electrical field permitivity of the insulator between the plates.The insulator characteristics may generally change with frequency but that is not our discussion.
4. ### Understanding the capacitor deeply

hello every body, i am trying to understand the capacitor behavior as deeply as i can ... consider a simple capacitor with two plates A and B ---| |--- 1- why the charge on both plates are equal in magnitude ? when we apply a voltage to a capacitor,charge will accumulate on side A.this...
5. ### Voltage Limiter Circuit

I am asking this for my own ... what's the advantage of the dropout regulator if it drops the Vout to zero when the input goes down? He wants to maintain the Vout same to Vin if Vin goes under some threshold.So Why a simple zener regulator is not enough?
6. ### Voltage Limiter Circuit

i just give the idea... all you need is number of zener diodes man.so that their total sum of reverse voltages is 18 volts. this is the simplest limiter. for Vin>18 the zeners will turn on and sink current and Vout reamins at 18 volts.for Vin<18 the zeners are just not enough reverse biased...
