Current Electricity - Concept Builder 1

According to Ohms law the potential difference across a conductor is directly proportional to the current through the conductor. Hence resistance is R= V/I. the potential difference across the conductor is first determined without connecting the voltmeter. The potential difference is observed connecting the voltmeter. Then the percentage difference is calculated. Learn more at www.youtube.com

ATtiny45blinkled.AVI

works with 5 v. the tutorial for the ATtiny 45 is found at imakeprojects.com My circuit can be found at .....later I will update this video. The LED's (30 led's) were bought at walmart. Actually is part of a kit that I used for my design purpose. The total current for all LED's is around 350 mA. By ohm's law you can use a 5v entering the relay and divided by 350mA to get a 14ohm resistor Well, I used a 100 ohm resistor in series to be safe an extent the life of the LED's ...
