The LED parameters are: ULed is 3V, Current 100mA
Take measures so that the LED at the U 12V supply is not destroyed. Perform the calculation and also the wiring diagram.

Correct answer:

R =  90 Ω

Step-by-step explanation:

U1=3 V U2=12 V I=100/1000=101=0.1 A  U=U2U1=123=9 V U = RI R=IU=1019=90 Ω
