620%238%20(1).pdf 1 / 4 100% + Homework #8 – LED Circuits NOTE: to solve the problems you will use the following assumption 1) A LED (disregarding the color) need at least If=5mA or more nsure that the LED lights up 2) The standard value of the current for the nominal work of a LED (disregarding the color) is 20 mA 3) These are the values of the Voltage Forward of the LED by colors. This voltage ensure that the LED conducts and lights up. In this exercise Vf will not depends on the current If (in real life Vf changes but not significantly with the current) a. Vf(RED) = 1.9 Volts b. Vf(YELLOW) = 2.1 Volts c. Vf(GREEN) = 2.3 Volts d. Vf(BLUE) = 3.4 Volts e. Vf(WHITE) = 3.9 Volts Problem #1 Given the Circuit 1 R1 D1 RED- BAT1 MacBook Air DII DD
