I'm in bit of a pickle with this problem
In the circuit in the attached photo
a) Is the voltage (potential difference) enough in point a so you can be sure the diode has a voltage drop of 0.7V?
b) Determine the current Id through the diode
c) Determine the voltage (potential difference) in point a.
I'm not really sure how I would go about solving this. I think the answer to a) is yes and in b) I get 3.02*10^3A. c) 14.89V
I'm not sure however how I can calculate a) without knowing if there is a 0.7voltage drop in the diode or not. Furthermore I don't see if in b) c) I can just use 300.7=Rtot*Itot and just use ohm's law to figure out the rest?
All help really well appreciated!
