Hello,
I am a computer engineer that specialized more in software but I am trying to remember the electronics part.
In the book I read there is an exercise where a diode (forward-biased) is connected in parallel with a resistor and then both of them are connected in series with another resistor.
This simple circuit is connected to a dc power source.
If I consider a voltage drop on the diode (either 0.7 or 0.3, etc) the value of the current that passes through the diode, I can calculate it correctly.
The problem is when I can think of the diode as being ideal (with 0 drop voltage). In this case I can't seem to find the value of the current that passes through the diode (as in the answer).
If the voltage drop on the diode is 0 can I consider the circuit as with no diode (2 series resistors connected to a dc voltage source)?
If the voltage drop is 0, the voltage on the resistor connected in parallel with the diode will also be 0 ?
