🔍 Key Concepts

• TRIAC operation as a bidirectional AC switch • Relationship between TRIAC and SCR (silicon-controlled rectifier) • How conduction direction (one-way vs two-way) affects the internal equivalent circuit

💭 Think About

• Ask yourself: Does a TRIAC conduct current in one direction like a standard SCR, or in both directions? How does that influence its internal equivalent circuit? • Which option best matches a device that can be triggered into conduction in EITHER direction on an AC waveform using a common control terminal? • Consider how an SCR is structured internally. What would you need to change or 'add' to model a device that works on both the positive and negative half cycles but still uses one gate/control lead?

✅ Before You Answer

• Check which options are bidirectional vs unidirectional in how they behave with current flow. • Verify which option explicitly involves an SCR-like structure and a common gate/control element. • Eliminate any options that describe components (like specific transistor or capacitor arrangements) that do NOT obviously explain symmetrical conduction on AC.
