Question 1: One BJT, of the current gain ß = 60, is supplied by two voltage

sources VBB = 8V and Vcc= 15V.

a/ Calculate the base current IB, the collector current Ic and the voltage

VCE.

b/ Calculate the dissipated powers Po on the BJT, PRC on the resistor Rc.

and the power Pcc supplied by the source Vcc.
