I'm a little confused about the following problem if I'm approaching it in the right way:
I need to find voltage across R2 and here is my approach.
First I figured out that diode is forward bias and Vtotal=5V-0.7V=4.3V
Than I calculated total current I=4.3V/23kΩ=0.187mA
To calculate votage across R2=0.187mA*1kΩ=0.187V
Did I do this correctly? This problem is a multiple choice and the number I got is not among the listed ones. I'm trying to figure out the approach rather than a straight answer. Thanks.
