🔍 Key Concepts

• Examine how CR1 is connected relative to the load RL and the transistor Q1 • Think about the typical role of a diode (or zener diode) placed across a load in a DC power-supply regulator circuit • Compare the function of the rectifier diodes D1 and D2 with the role played by CR1

💭 Think About

• Is CR1 in the main current path from the transformer/rectifier to the load, or is it connected in a way that suggests it is sensing or clamping voltage? • If the circuit’s goal in section D is regulation, what does Q1 need in order to maintain a stable output at TP5? • Which component(s) in the earlier sections (A–C) already handle rectification and filtering, and therefore do NOT need to be repeated by CR1?

✅ Before You Answer

• Trace the polarity and orientation of CR1 relative to RL and ground; is it forward or reverse biased during normal operation? • Verify which component is directly responsible for converting AC to DC (rectification); check D1/D2 vs CR1 • Ask whether CR1’s placement would more likely provide a reference voltage or handle ripple smoothing/rectification
