For all problems, assume: the LEDs are red LED with a forward

For all problems, assume: the LEDs are red LED with a forward voltage of 1.7 V. transistor parameters are VBE=0.7 V, VCE(sat) 0.2 V, and -200 1. Consider the circuit shown on the right. (a) Draw the equivalent circuit diagram where the only components are resistors, voltage sources and current sources. (b) You'd like to drive the LEDs with a current of 10 mA; find the value of the resistance R2 that will make this happen. (c) You'd like the current through the Zener diode to be 40 mA; find the value of the resistance R1 that will make this happen. (d) Find the power dissipated in each resistor (e) What standard resistors should you use for R1 and R2 (specify both resistance and power rating) 5.1V Zener +15V R1 R2
