    Graphic Circuit Simulator

    Hey all, I've found a applet for circuits simulations. This isnt your everyday circuit simulator. With this one you can build your own circuits and simulate, but when the simulation starts, it shows how the current and voltage interact in the circuit. It also has the ability to show voltage...

    How to derive ohms law

    Hey all, I'm curious. How can ohms law be dervied. The only way I can do it is by experiments. How do we arrive at V = IR without any experiments. Thats all  ;D --thank you.

    High Quality electronic sites

    Hey all, I scrap my first project that I posted some time back. I started a new one called Free Engineering Online. It contains links to engineering, physics and math video lectures. There are also links to tons of ebooks. There is also a Discussion Board to go along with it.

    frequency detector software

    I havent really given that aspect any thought. I just wanted to "mess around" a little. But since you asked - things like cell phones, cordless phones, radio waves. I guess all of these are above 1KHz.

    frequency detector software

    Hey all, Is there such a software package that uses the computer's wireless card to detect frequencies - not internet signals coming from a router, but other frequencies floating around. --thank you.

    LED dimmer

    So youre trying to minimize power dissipation. So now I must ask how would you choose whether to leave the transistor fully on or off? Yes, that would great.

    LED dimmer

    Is this parameter known as PDmax? I dont really understand why this is so. Also why did you use half the max current?

    LED dimmer

    It makes sense now. Thanks for youre help  :) btw, I noticed that you used some dashed lines in the schematic (LED section). Does this mean that I can have as many LEDs without changing component values?
