Step a: Calculate the Thevenin equivalent resistance between points a and b (RTh(a,b)) [Ω] and between points b and c (RTh(b,c)) [Ω]. Use the circuit diagram of figure 2.
Step b: Calculate the Thevenin equivalent voltages between points a and b (VTh(a,b)) [mV] and between points b and c (VTh(b,c)) [mV]. Use the circuit diagram of figure 1. Keep Switch 1 and Switch 2 open.
Step c: Calculate the voltage across resistor R5 (VR5) [mV] and the voltage across resistor R6 (VR6) [mV]. Use the resistance values from step a as follow R5 = RTh(a,b) and R6 = RTh(b,c). For the calculation of VR5 close Switch 1 and leave Switch 2 open. For the calculation of VR6 close Switch 2 and leave Switch 1 open. Use the circuit diagram of figure 1.
Step d: Calculate the maximum power absorbed by resistor R5 (PR5) [μW] and the maximum power absorbed by resistor R6 (PR6) [μW]. Use the resistance values from step a as follow R5= RTh(a,b) and R6 = RTh(b,c)
