    Some general questions...

    Hey guys!!! Back again... Here are my queries. 1) In a final amplifier how we measure the aid of the forse? (show me a way to do it,for an example at a simulation program,and of course at the reality) 2) What are the materials which i must use and also what should be their proportions in...

    Multisim 2001 and spice

    hello experts!!! i have Miltisim 2001 and i need some informations for the way that program is using spices.which version is using the Multisim? pspice? i dont know very much about them :( i try to solve a problem at my design which is a power amplifier.i cant manufacture the 2 mosfets,1 fet...

    Why?

    hello! 1st question: why we usually find a capacitor at the motor of a radio control car? we want to increase the capacitance,and why this? for better compensation? an opinion? 2nd question: i want to place a more powerful motor.i must to increase the current?a simple circuit for this? thanks!

    HOW??? :-(

    Thanks Sebi,but.... i know that.i can't do this only with capacitors.propably i don't know this.i have this circuit and i can't explain how that's happend.can you see that and tell me? thanks :?

    HOW??? :-(

    can somebody explain me how with the use of big capacitors we can make high voltage from low?p.x. at the supply of a power amplifier.if you can,a circuit example please with explanation? :( Thanks a lot!!!

    A help here? Wilson sourse? :(

    Who do Wilson sourse works at a diff.amplifier?An examle please if you can.another question:how many mV can i put at the input of a power amplifier to test the amplifier with Multisim 2001?Thanks!
