Thank you Thank you all for ur responses. It is now clear to me. These were some good and solid answers.

Thanks corneo, but it is the mathematical explanation. I want to understand it physically as i said earlier.

How can we explain the blocking of a dc current by a capacitor and passing through of ac, physically, not mathematically. In case of dc we know that the capacitor will initially act as a short circuit till it gets charged fully and then naturally acts as an open circuit since it cannot be...

Reply I have read much about SCRs, their turn on and turn off methods and characteristics. Also I know about triggering an scr (Firing circuits), etc. This question was posed by my teacher. He asked whether we can drive an scr through a microprocessor, i.e., control it by a microprocessor...

How can we control an SCR through a microprocessor with an opto coupler used as an 'isolating and amplification' device between the microprocessor and the SCR.
