What does it mean for a transistor to be cut off?

🔍 Key Concepts

• Relationship between base current and collector-emitter current in a transistor • What happens to the collector-emitter path when the transistor is in cutoff versus saturation • How a transistor behaves like an open switch versus a closed switch

💭 Think About

• If you think of the transistor as a switch, what does the current between collector and emitter look like when the switch is "off"? • Does having no base current automatically guarantee a specific condition between collector and emitter, or is the key idea what happens in the collector-emitter circuit? • Which option best describes the state of current flow through the main path of the transistor when it is not conducting at all?

✅ Before You Answer

• Identify which choice directly describes current between emitter and collector, not just the base • Make sure the description matches an open switch condition, not a partially on or fully on condition • Eliminate any answer that implies maximum or normal operating current through the transistor’s main path
