Okay so here's what I am dealing with. I created a circuit with 3 volts and used a 330 ohm resistor and a simple red LED, and using my multimeter I tested for the current. Now using ohms law:(adsbygoogle = window.adsbygoogle || []).push({});

3/330 = 9 mA..... now what I see over the multimeter is 3 mA. I must have calculated something wrong or something is different with in the circuit. Maybe because a load is there, the calculations totally change?
