Diode Test and LED Burning Simulator for 5V and 9V DC withdiode

Here's a simple circuit setup to test diodes and simulate burning a red LED with both 5V and 9V DC power sources: ## Basic Diode Test Circuit For testing regular diodes: ``` Power Source (+) → Resistor → Diode (anode to cathode) → Power Source (-) ``` ## Red LED Burning Simulation Warning: This may damage the LED - for simulation/experimental purposes only Components Needed: - Red LED (typical forward voltage ~1.8-2.2V) - Current limiting resistor (optional for protection) - 5V DC power source - 9V DC power source - Multimeter (for current measurement) Circuit Setup: 1. Without Resistor (Direct Burn Test): ``` 5V/9V (+) → LED (anode) → LED (cathode) → 5V/9V (-) ``` - This will likely burn the LED quickly - Current will be limited only by LED's internal resistance 2. With Current Limiting (Safer Test): ``` 5V/9V (+) → Resistor → LED → 5V/9V (-) ``` - For 5V: Use ~150Ω resistor (limits current to ~20mA) - For 9V: Use ~330Ω resistor (limits current to ~20mA) ## Observations: 1. At 5V: - LED will light brightly - May burn out after prolonged exposure - Current will be higher than rated if no resistor 2. At 9V: - LED will likely burn out almost instantly without resistor - Even with resistor, may reduce lifespan significantly ## Safety Notes: - Always use current limiting resistors for normal operation - Burning LEDs produces heat and may release fumes - Damaged LEDs may fail short or open circuit - This is for educational purposes only - normal operation should stay within LED specifications Would you like more specific details about any part of this simulation?
