In this problem's solution, I can't understand why the lamp's resistance is used to calculate the voltage of the diode: I assumed it would be the other way around: Since the current is the same in the whole circuit, because the connection is in series, then I could apply Ohm's Law on the lamp, with the lamp's resistance and the current of the diode, to obtain the voltage of the lamp. What am I not getting here? I upload the letter of the exercise, along with the solution, in a file. Thanks in advance.
