How the Circuit is Series and Parallel
- Series in Each Group:
- Each group of LEDs (e.g., Red, Green, White, Blue, Yellow) is connected in series. The LEDs in a group share the same current, and their forward voltages (VfV_fVf) add up.
- Parallel Across Groups:
- Each series group is connected in parallel to the 12V power supply.
- The groups operate independently, meaning if one group fails, the others continue to work.
- The current for each group is determined by its series resistor.
Current Calculation for Each Group:
1. Red LEDs (5 in Series):
2. Green LEDs (5 in Series)
3.Blue LEDs (5 in Series)
4. Yellow LEDs (5 in Series)
