🔍 Key Concepts

• Photoconductive effect in semiconductors and crystalline solids • How light (photons) can change an electrical property of a material • Where you encounter light-sensitive components in basic electronics (e.g., light-dependent devices)

💭 Think About

• When light shines on a crystal and frees charge carriers, which electrical property of the material changes in a simple circuit? • Think of common light-sensitive components in circuits: what parameter of those components changes as light level changes? • Which of the four options is the one most directly related to how easily current flows through a material?

✅ Before You Answer

• Identify which option is the property most directly tied to current flow vs. applied voltage in a material. • Recall that photoconductive materials become better conductors when illuminated – what quantity is that describing? • Make sure the option you choose is something that realistically could change quickly with light in an electronic component, not a bulk physical property like mass or density.
