🔍 Key Concepts

• LED (Light Emitting Diode) operation – what makes it give off light • What physically happens when an LED "burns out" or fails open/short • Difference between normal emission, reduced emission, and no emission

💭 Think About

• If an LED is burned out, think about whether it can still pass current to create visible light at all. • Look at the wording of each choice: which describe more light, which describe less or none? • In a failed (burned-out) semiconductor device, would you expect it to get brighter, dimmer, or stop working altogether?

✅ Before You Answer

• Eliminate any option that suggests increased or excessive light output when a device is failed. • Consider whether a slight glow means the component is still partially working rather than fully burned out. • Focus on which choice clearly indicates complete failure of light output rather than just a change in brightness.
