I know that Ohm's Law is V = IR but I am getting some very confusing current readings from multiple multimeters. Here is my very basic breadboard configuration:
V = 6v
R = 200 Ohms
I = Should equal 30 mA but it does not (see multimeter pic)
The multimeter shows 18.8 mA but I do not know why. I have also tried with 3.3v and it registers 6.6 - 7 mA.
I would like to know why this is happening. I have tried different resistors, LEDs, multimeters, breadboards, power supplies but it continues to happen and I am very confused with the readings.
