$1-$ For the network in this Figure, determine:

$($a$)I_B.$

$($b$)I_C.$

$($c$)V_E.$

$($d$)V_{CE}.$

$2-$ For the network in this Figure, determine:

$($a$)V_E.$

$($b$)I_E.$

$3-$ For the network in this Figure, determine:

$($a$)I_E.$

$($b$)V_C.$

$($c$)V_{CE}.$

$4-$ Using the specifications in this Figure, design a voltage divider configuration to have a saturation level of $10$ mA and a $Q-$point halfway between cutoff and saturation. The current supply is $28$ V and $V_E$ will be one$-$fifth of VCc$.$
