Lesson 6 error (minor)

Post by -nkt- »

Minor error in lesson 6

Code: Select all

Now change it to 100Ω, and solve again! This time try to do it yourself without my help.
Highlight the text below for the answer
Lets use Ohm's law again: V = 9, R = 1,000 which means we can go ahead and solve for I. V = IR -> I = V/R = 9/1000 Amps = 0.009 Amps = 9 mA
Since that's the same answer as the previous question using 1000 ohms, the answer should be 90mA.

(If anyone's paying attention, you'll see I'm working my way through the tutorials rather nicely. They are great! All basic electronics and programming stuff so far, but the mix of the two is a great intro to this dark art of microcontrollers. Just what I needed.)
