65 parts in 10 categories. Open each one up, look at its pins, and learn which value it is used with, where, and the most common mistake.

9 V · RED LEDNORMAL
14.9 mA
I = (9.00 V − 2.01 V) / 470 Ω = 14.9 mA

The 470 Ω resistor is protecting the LED. Take it out, put a wire in its place and see what happens. Burning out a virtual LED costs nothing.
