LED States in Current and Reverse Bias Circuit

Click For Summary
SUMMARY

The discussion focuses on the states of six LEDs in a circuit under current and reverse bias conditions. LEDs 4, 5, and 6 are confirmed to be ON, while LEDs 2 and 3 are OFF due to high resistance in LED 2, which is reverse biased. The question arises regarding LED 1, which is in series with LEDs 2 and 3, and whether it can conduct current independently. The conclusion reached is that LED 1 will also be OFF due to the series connection limiting current flow.

PREREQUISITES
  • Understanding of LED behavior in series and parallel circuits

Homework Statement


Indicate which of the 6 LEDs are ON and which are OFF


Homework Equations


V=IR


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?
