🔍 Key Concepts

• Thermal runaway in semiconductor devices (what causes it) • How temperature affects transistor leakage current and collector current • Methods of heat dissipation and bias stabilization in transistor circuits

💭 Think About

• Which option would help keep the transistor’s temperature from rising further once it starts to heat up? • Which choices would actually make current (and therefore power dissipation) increase instead of decrease? • Think about which method is commonly used in power electronics to remove excess heat from components.

✅ Before You Answer

• Identify which options would increase current and power, and eliminate them. • Consider which option is a mechanical/thermal solution rather than an electrical bias change. • Ask whether the action would make the transistor run cooler or hotter under load.
