Quick basic question.

How do you calculate the current in this circuit you know the resistance values of the resistors and voltage of vs and you know the voltage drop across the forward biased diode is 0.660v how do you give it a resistance value to find total current ?

hi,
You dont need to know the diodes resistance.

Subtract 0.66V from 5V and divide the result by the total value of the fixed resistors
