🔍 Key Concepts

• Junction field-effect transistor (JFET) vs. other types of FETs • Difference between channel type and material type (silicon, germanium, etc.) • How JFETs are categorized in basic electronics theory

💭 Think About

• Ask yourself: In textbooks, when JFETs are first introduced, how are they usually classified into two main groups? • Which answer choices describe how the current flows through the device, rather than its construction material or power rating? • Which options mention device types that are actually different FET families, not subtypes of JFETs?

✅ Before You Answer

• Verify which option refers to channel polarity (type of majority carriers) in the device. • Check whether any choice is mixing JFETs with other FET technologies such as MOSFET (metal-oxide-semiconductor FET). • Confirm that the two "basic types" are about how the JFET operates internally, not about power level or semiconductor material.
