1. The problem statement, all variables and given/known data https://www.edx.org/static/content-mit-6002x/images/circuits/diode-limiter.013c535f04ae.gif [Broken] The AC voltage source puts out a symmetrical triangle wave that looks like: https://www.edx.org/static/content-mit-6002x/images/circuits/triangle-wave.52377c602e8e.gif [Broken] The peak voltage of this waveform is 9.5V. The resistors both have the resistance R=4.7kΩ. The voltage of the DC sources is V1=3.0V and V2=2.0V. They ask for the maximum current that can go through both diodes(both through D1 and D2). They also ask for the maximum positive and negative voltages across R, but I got that already. 2. Relevant equations Standard: KCL, KVL, blah blah blah.... 3. The attempt at a solution OK. So if the maximum current is going through a diode, it acts like it's a short. I assume that the other diode would act like it's an open branch, so I can disregard that. From there, I use KCL to solve. I get a ridiculously small amount of current(in Amperes), that is wrong. What am I missing?
