What is the current in the circuit if the LED measures 2 volts?

Draw a series circuit with a 6v battery, an LED and a 330 ohm resistor. What is the current in the circuit if the LED measures 2 volts?

I was able to draw the circuit but I am looking for help with the calculation

    v=6v

    Vled=2v

    Vr=4v

    I=4/330=.01212=12.1mA.

    voltage across the resistor is 6 – 2 = 4 volts

    I = E/R = 4/330 = 0.012 amps or 12 mA
