We have two circuits in the figure. For each find I and V. The answers are
This isn't homework,before you tell me to add this to the homework.I just found this and I want to know how to solve this.They look similar to the logic gates,the first one to OR gate and the second to AND gate,but where do I go from there?
It's digital logic, 3 being High and 1 being Low, anything in between won't have much effect.
The left side is an OR gate. So its kinda like High or low = 1 or 0 = High
High being 3 volts, and low being 2 or 1 volt relatively speaking.
In the latter, right side, is like an AND gate, So it's kinda like High and Low = 1 and 0 = 0
Again, High being 3 volts and Low being 1 volt.
The provided answers (3 mA, 3V and 4mA +1 V) assume ideal diodes -- no voltage drop when forward biased and no current when reverse biased.
In the left diagram, the diodes connected to 1 & 2 volts are reverse-biased and so the only current flowing is from the 3 volt source.
In the right diagram, the diodes connected to 2 & 3 volts are reverse-biased and so the only current flowing is into the 1 volt source.
