Show hintHide hint
Think about the type of charge carriers mentioned.
4Question 4.
True or False: The base-emitter junction is typically reverse-biased in normal operations.
- True
- False
Show hintHide hint
Recall the biasing conditions of the junctions.
Question 5.
Consider a BJT with a forward-biased base-emitter junction of 0.7V, derive the current using the diode equation.
Show hintHide hint
Remember the thermal voltage at room temperature is approximately 25mV.
Question 6.
You have a BJT with a known collector current of 5mA and a beta (current gain) of 100. Calculate the base current.
Show hintHide hint
Focus on relationships between different currents in the BJT.
