➄ The “a2” coefficient of the Linear Fit line is the slope of the linear region. Record the value of
the slope.
• The slope can be interpreted as follows:
slope =
∆I
c
∆I
b
= β
where β is called current gain of the transistor.
➅ Record the current gain of the 2N3904 transistor.
current gain = __________
Questions
➀ How does the general shape of the plot for the transistor compare to the plot of current versus
voltage for a diode?
➁ What is the current gain of the 2N3904 transistor?
