Consider the LED circuit below (shown in Fig. ) which is driven by a 5V connection from a controller (supply). The LED has a forward voltage of 1.7V and should run on continuous current of no more than 10mA. Calculate the resistance R2 (showing relevant calculations and steps) required for the LED to run on that continuous current. Assume that R1 has a resistance of X -ohms where, (X = last non-zero digit of your student no. * 10) (e.g. if your last non-zero digit is 4 then R1 is 40-ohms): R1 V1 5V ΧΩ 41₁ R3 1k92 R2 LED1 Consider the LED circuit below (shown in Fig. ) which is driven by a 5V connection from a controller (supply).
