1/Be accurate when you deal with load-line analysis.
2/ Check the value of the voltage source and the direction of the current in both series and parallel configuration.
3/ In case of reverse bias : Vd= E and Vr=0 , but if there are two diodes are series in different directions ( Example 2.8) , the reversed one = E , and the forward will be zero.
4/Be careful with directions
5/In parallel :
same type , same direction = Both on or both off
same type , Different direction = when the direction of the current of circuit is the same of one diode ( on ) and the other ( off). Different type , same direction = The one with lowest Vk ( on ) , the other ( off) .
6/ Full-wave biased rectifier, using silicone instead of ideal , there will be a small area in between each wave + you should consider this voltage while talking about (on - off conditions) ( see our quiz )
7/ There is no cut in series clippers, while in parallel biased clippers there is ( check slide 50 and 51)
8/ You know clampers by seeing the capacitor.
9/ In clampers, start when the diode is on --->find Vo -----> find the charge in capacitor ----> change polarity of Vi -------> find Vo
10/ Zener works in reverse bias
11/When Vi> Vz , zener is on otherwise it is open circuit.
12/ You can find VL by voltage divider rule , check if it is > Vz
Yes: VL = Vz No: VL= VL , the zener is off
