Question
Given below is a schematic for a simple LED flashlight, as well as the values therein. If the LED would bum out at curents above 12 milliamperes. 12 V R1 + 12 mA R2 1. What is the entire circuit's current if the total resistance is zero? 2. How much resistance is nooded to koep the LED from burning out? 3. How much power does the LED use? 4. Determine the resistance of the second resistor if the finst resistor is four (4) times higher resistance than it.
