🔍 Key Concepts

• LED (Light Emitting Diode) works like a regular diode in terms of current direction • Difference between forward bias and reverse bias in a diode • What electrical condition causes current to flow through a diode and allow it to emit light

💭 Think About

• Think about in which bias condition a diode normally conducts current and allows charge carriers to recombine. • When does an LED actually light up in a practical circuit: how are the anode and cathode connected to the power source? • Which of the options refers to a general conduction condition for diodes versus specific logic-level signals in digital circuits?

✅ Before You Answer

• Verify which bias condition (forward vs reverse) allows current to flow through a diode under normal operation. • Check whether logic 0/logic 1 directly describe diode biasing, or if they are more related to digital signal levels. • Confirm that luminescence in an LED is tied to carrier recombination that happens only when the diode is conducting normally.
