3 cards from this section. Quick, good the night before a test.
What indicates a BJT is in cut-off region?
Think about the switch being off.
What is the saturation region in a BJT?
It’s like a switch being closed.
What state does a BJT represent when in the cut-off region?
Relate this to a common household switch.
A BJT in saturation allows maximum current flow. True or False?
Think of a closed circuit.
Design a circuit that uses a BJT as a switch to control a light bulb, specifying resistances and the power supply needed.
Start with Ohm's law and current gain formula.
Evaluate how the temperature in a circuit can alter the performance of a BJT used as a switch.
Consider how heat influences conductivity and resistance.
