Can anyone give a hand with H3P4: DIODE LIMITER, trying to find the current through Diode 1 and 2 in this circuit - https://6002x.mitx.mit.edu/static/circuits/diode-limiter.gif

where R = 5.6k
V1 = 3.25v
V2 = 3v

Peak voltage of AC source is 7.5V

Any help on how to do the thevenin method would be great

anonymous · Answer

D1: (Vs-V1)/R - V1/R
D2: (-Vs+V2)/R - (-V2)/R 
*remember to look at the directions of the diode arrow
Hope this helps
