I think you didn't account for the 10 V battery that gets placed in between A and B. I just don't understant why R2 and R3 become parallel to each other after placing the battery. So the answer is actully to add R1 and R2 and then find the Parallel ones, so Req = (1/(R1+R2)+ 1/R3)^-1. My question is how do you know which one you do first? Adding the parallel ones or the serial ones?

- According to its design specification, the timer circuit delaying the closing of an elevator door is to have a capacitance of 32.0 F between two points A and B.

To meet the specification, one additional capacitor can be placed between the two points. (a) Should it be in series or in parallel with the 34.8-F capacitor? (b) What should be its capacitance?
