🔍 Key Concepts

• Identify how section D of the circuit functions in a regulated DC power supply (series-pass regulator using transistor Q1). • Compare the schematic symbol of CR1 with a normal rectifier diode symbol and with a zener diode symbol from your reference sheet. • Think about which device is normally used to provide a fixed reference voltage to control the base of a pass transistor in a simple DC regulator.

💭 Think About

• What is the job of CR1 in this part of the circuit: is it rectifying AC, triggering a device, or providing a nearly constant reference voltage? • Look at where CR1 is connected: is it in the AC input path or across a DC point to ground? How does that location match the typical use of each option (rectifier diode, diac, zener diode, tunnel diode)? • Which of the four choices is most commonly used in basic linear DC power supply regulators to keep the output voltage steady despite load or input changes?

✅ Before You Answer

• Verify the symbol shape of CR1 against standard symbols for rectifier, zener, diac, and tunnel diodes in your exam reference. • Confirm whether section B of the drawing already contains the main rectifier diodes for AC-to-DC conversion, and what that implies about CR1’s function. • Make sure the device you choose is one that is typically used in low‑voltage DC regulators rather than in high-speed switching or special triggering circuits.
