I need to calculate the circuit below. (The used diode in the schematics is not the same from the task we have to solve. In our task we work with a ideal diode.)
In school we learned, that a ideal diode could be substituted with a normal voltage source with the forward voltage of the diode (in our case 0.7V). Now I am not sure how to solve this task and how would a general approach on solving such problems look like?
According to the solution, the voltage meter should show V = 3.975V and I = 198.75uA
