Solucion:

a)

\begin{displaymath}V_{B}=V_{CC}\,\frac{R_{2}}{R_{1}+R_{2}}\end{displaymath}
 
\begin{displaymath}R_{B}=\frac{R_{1}\,R_{2}}{R_{1}+R_{2}}\end{displaymath}


\begin{displaymath}V_{B}=R_{B}\,I_{B}+V_{BE}+R_{E}\,I_{E}=R_{B}\,I_{B}+V_{BE}+R_{E}\,(\beta+1)\,I_{B}=(R_{B}+R_{E}\,(\beta+1))\,I_{B}+V_{BE}\end{displaymath}

 

Los puntos de corte con los ejes de la linea de carga del transistor en $V_{BE}/I_{B}$


\begin{displaymath}V_{BE}(I_{B}=0)=V_{B}\end{displaymath}

 

\begin{displaymath}I_{B}(V_{BE}=0)=\frac{V_{B}}{R_{B}+R_{E}\,(\beta+1)}\end{displaymath}

 

Los puntos de corte con los ejes de la linea de carga del transistor en $V_{CE}/I_{C}$
 

\begin{displaymath}I_{E}=I_{C}+I_{B}=I_{C}+\frac{I_{C}}{\beta}=I_{C}\, \frac{\beta+1}{\beta}\end{displaymath}
 
\begin{displaymath}V_{CC}=R_{C}\,I_{C}+V_{CE}+R_{E}\,I_{E}=R_{C}\,I_{C}+V_{CE}+R...
 
\begin{displaymath}I_{C}(V_{CE}=0)=\frac{V_{CC}}{R_{C}+R_{E}\, \frac{\beta+1}{\beta}}\end{displaymath}
 
\begin{displaymath}V_{CE}(I_{C}=0)=V_{CC}\end{displaymath}

 

Si aumenta un poco $R_{C}$, el punto$I_{C}(V_{CE}=0)$ disminuye un poco lo que implica que la linea de carga del transistor baja un poco. Con lo que la $V_{CEQ}$ se desplaza un poco hacia la izquierda con lo que disminuye su valor.
