When the diode is forward biased, then the diode has a very low resistance, about 100 ohms. Most resistors have a much higher resistance, so when a forward-biased diode and a resistor are in series, as in the this circuit, the total resistance is pretty much the same as the resistor’s resistance. Thus, the amount of current that flows is determined by Ohm’s law (V =I*R) where R is the
