🔍 Key Concepts

• Intrinsic semiconductor behavior (pure semiconductor without added impurities) • Relationship between free charge carriers (electrons and holes) and temperature • Difference between material properties (conductivity/resistivity) and AC circuit properties (inductive/capacitive reactance)

💭 Think About

• As temperature increases in a pure semiconductor, what happens to the number of electrons that can jump into the conduction band? • If more charge carriers become available, how would that affect how easily current can flow? • Are inductive and capacitive reactance properties of the semiconductor material itself, or of separate AC circuit components like coils and capacitors?

✅ Before You Answer

• Make sure you connect temperature to the number of charge carriers in an intrinsic semiconductor • Decide whether increasing temperature makes current flow easier or harder through the semiconductor • Eliminate any options that clearly relate to coils (inductors) or capacitors instead of the semiconductor material itself
