From information found in the 2N3904â€™s datasheet (found withGoogle or on Blackboard), estimate the collector-emitter saturationvoltage of the 2N3904 transistor at a collector current of 15 mA.You may perform a linear interpolation between the values found inthe datasheet (ie: use the point-gradient formula learned in highschool).

Answer:

As Per Fairchild semiconductor datasheet of 2N3904Â Â transistor

V_CE(sat) Collector-Emitter Saturation Voltage =0.2V for I_C = 10 mA

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â =0.3V for I_C = 50 mA

Using Point Gradient Formula

m=y₂-y₁/x₂-x_{1Â Â Â Â Â Â Â Â Â Â Â Â Â} where y₂=0.3 and y₁=0.2

x₂=50 and x₁=10

Therefore m=0.0025

Similarly for I_C =15mA , V_CE(sat)=?

Using the above formula here y₂=0.3 and y₁=unknown

x₂=50 and x₁=15

m=y₂-y₁/x₂-x₁

0.0025=0.3- y₁/50-15

y₁=0.212

therefore V_CE(sat) Collector-Emitter Saturation Voltage =0.212V for 15mA
