Question

H3P4: Diode Limiter
is there any one to guide me to solve it?

Answer 1

When voltage source is +7.5 then only D1 will work,now apply thevenin's process and find the current.and for -7.5 only D2 will work.

Answer 2

For D2=(-V2/R)-((V2+Vin)/R)

Remember who is conducting and use LCK

Answer 3

v2=3
r=5600
vin=???? 7.5/ \[\sqrt{3}\]

Answer 4

Vin = 7.5

Answer 5

ID2=-0.002411A its wrong answer

Answer 6

(-Vs=V2)/R-(-V2)R = (-7.5+3)/5600 -(-3)/5600 = -0.000268
however the diode is going in the opposite direction therefore the ans should be 0.000268

Answer 7

take the negative sign and thats it

Answer 8

Anyone can help me with the lab?
