Consider the circuit above where the LED is powered from a +5 V DC voltage. Assume that the LED is the LTL-4263 from Lite-On. a) When using LEDs a series resistor is often included as a current limiting device to prevent the LED from burning out. We wish to have a current of 1 = 20 mA under typical operation, what value of resistor should be used? Assume that you must use 5% tolerance resistors (E24 preferred values). b) What is the DC power dissipated in the LED? Express this in both mW and as a fraction of the maximum allowed power dissipation of this particular LED. تی 5V يشمه D1 Consider the circuit above where the LED is powered from a +5 V DC voltage.
