6.1 Growth Models Score: 3/18 Answered: 3/18 • Question 5 < > Imagine two populations, A and B, each starting (now) with the same number of people. • Population A starts with 55000 people and grows linearly by 2500 people per year. Population B also starts with 55000 people, but it grows exponentially by 1.7% per year. If t represents the number of years after today, then population A can be modeled by which equation? f(t) = 2500(55000)* f(t) = 55000+2500t f(t) = 55000(2500)* f(t) = 55000t + 2500 Submit Part A Part 1 of 5

Determine an expression for $R_{B1}$ and $R_{B2}$ to yield a particular $I_C$ Determine expression for $R_{IN}$ with respect to $R_{B1}$ and $R_{B2}$. For a collector current of 1mA find $R_{B1}$ and $R_{B2}$, and $R_C$. Can you find $R_{B1}$ explicitly (no - explain why). 6.2 For the circuit above, determine $R_{B1}$ and $R_{B2}$ to maximize power gain. 6.3 Eliminate the capacitor between the emitter of the transistor and the ground. Re-write the small signal model. Determine, $R_{IN}$, $R_{OUT}$, and $A_v$.
