Homework Help: Current and Reverse Bias

  1. Apr 3, 2010 #1
    1. The problem statement, all variables and given/known data
    Indicate which of the 6 LEDs are ON and which are OFF

    2. Relevant equations

    3. The attempt at a solution
    Okay, I know LEDs 4,5 and 6 will be ON and LED 2 and 3 will be OFF but what about LED 1? Because LED 2 has a very high resistance as it is reverse biased thus no current flows, but would that mean current would still flow through LED 1?

    LED-s 1, 2, 3 are connected in series. Can the current flowing through LED 1 be different from the current which flows through the other ones?
