🔍 Key Concepts

• Crowbar circuit role in power supply protection • Difference between voltage reference circuits and protection circuits • What happens to the output of a power supply when a severe overvoltage is detected

💭 Think About

• Think about why it is called a crowbar—what does a real crowbar physically do if you drop it across two terminals? • Is the main purpose of this circuit to create a precise reference voltage, or to react to an abnormal condition? • In a power supply, when voltage goes too high, what action best protects the load quickly: fine adjustment or a drastic action at the output?

✅ Before You Answer

• Identify which options describe normal control or sensing functions versus an emergency protective action. • Ask which choice actually involves shorting or clamping the power line when voltage gets too high. • Confirm that a crowbar circuit is associated with overvoltage protection, not with providing a stable reference for regulation or chopping.
