    Diode voltage drop (connected in parallel with a resistor)

    @fbs7 I've noticed I can get the result he has, in that way but I think it is confusing and actually wrong (and thus i opened this topic), since up until this point in the book, if the voltage drop on the diode is less then 10% of the source voltage, he will consider it to be 0V. I am saying...

    Diode voltage drop (connected in parallel with a resistor)

    @fbs7 that is the problem. @vk6kro & @ Jony130 that is also my answer on 0v voltage drop (but not the author). @vk6kro regarding the simulation (i use multisim) I know it's different in the "real/virtual world". Thank you all. In conclusion the book result is wrong (if they consider 0V...

    Wanted to Change over careers to Physics Research at Age of 22 is it too late?

    Age is not an issue if you can imagine ;) The math won't be too difficult b/c you only need to calculate, not remembering theorems and understand the proofs like a mathematician. You should be fluent in differential equations above all. I am a computer engineer that is starting to hate...

    Diode voltage drop (connected in parallel with a resistor)

    The book is All New Electronics Self Teaching Guide. @fbs7 the aproximation for the ideal diode is (a). If I do the calculations considering a voltage drop of 0.7 on the diode (forward-biased), the result is as they say in the book. If I do the calculations considering a voltage drop of...

    Diode voltage drop (connected in parallel with a resistor)

    Thank you for the quick answers. This means the answer in the book is wrong (when the ideal diode is considered). They obtained a current through the diode less then current through the series resistor. There is also a note in the book that says it's ok to consider an ideal diode when the...

    Diode voltage drop (connected in parallel with a resistor)

    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...
