I really have no idea about this. I read it somewhere and uptill now i thought charging and discharging are both equally easy for capacitor.. pls do ans if you know the ans..

Pls tell me why is it easier for a capacitor to discharge rather than charge.?

thank u guys.. these answers really helped me.thanks again.

you said that electrons don't lose speed.but i thought the moving electrons collide with the nucleas of the matter which gives them vibrations and that vibration is turned into heat(for a resistor). that is why i had this doubt whether electrical energy is in the kinetic energy of the...

Does electrical energy reside in kinetic energy of electrons?

yes your statement completely describes nature of mosfet,i guess. i just read a statement that "mosfet can be in on state even if no current is passing through them." n i think i have understood now since Vgs only induces the channel(kind of controls resistance of the channel) and Vds initiates...

hello everyone, pls tell me "how can a mosfet be in on state even if no current os passing through it?" can it be explained by the fact that channel is induced by Vgs & current passes when Vds>0. so Vgs turns mosfet in on state and current is zero because Vds would be zero./ Thanks in advance.

pls explain me the concepts of ac ground,dc ground and virtual ground.?

thank you,thanks a lot. i have some more doubts on capacitors and i ll keep posting them here.. thanks again.

Why do capacitors charge exponentially? and do not explain by equations.
