hello everyone,
i am in disagree with someone over the calculations in the circuits i will discuss with you.
circuit #1:
here is the diagram:-

do you find it correct? please check it carefully. the circuit will only conduct between 2.3v-10v. frequency is 2hz and used diode is silicon so therefore voltage drop of 0.7v.
circuit #2:
here is diagram:-

do you find it correct?
5v = -0.7 + 2v -Vr
5v = 1.3 -Vr
-Vr = 5 - 1.3
Vr = -3.7
Vr is voltage drop across the resistor. i don't understand why answer is "-3.7"?
i am very grateful if you can tell me if these circuits are corrent... your approval means the other person i am having argument is wrong. many thanks.
cheers
