Answer: Applying KVL to the base loop we get ,
$V_{BB}-I_BR_B-V_{BE}=0$
Substituting the given values ,
$4-220I_B-0.7=0$
$\therefore I_B=\dfrac{3.3}{220}$
$\therefore I_B=0.015mA$
Now the collector current can easily calculated by the following formula
$I_C=\beta I_B$
$\therefore I_C=200\times 0.015$
$\therefore I_C=3mA$
Applying KVL to the collector loop , we get
$V_{CC}-I_CR_C-V_{CE}=0$
$10-3 \times 2 =V_{CE}$
$\therefore V_{CE}=4V$
