LED circuit calculation

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

Final 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
