+// Given data
+// 2N3904
+Bdc=100;// current gain
+Vcc=10 ;// supply voltage in volts
+Ic=10*10^-3;// collector current in amperes
+
+// Calculations
+Ve=0.1*Vcc;// emitter voltage in volts
+Ie=Ic;// collector current is equal to emitter current
+Re=Ve/Ie;// emitter resistance in ohms
+Rc=4*Re;// collector resistance in ohms
+R2max=0.01*Bdc*Re;// in ohms
+V2=Ve+0.7;// in volts
+V1=Vcc-V2;// in volts
+R1=(V1*R2max)/V2;// in ohms
+disp("Ohms",R1,"R1=")
+disp("Ohms",R2max,"R2=")
+disp("Ohms",Rc," Collector Resistance=")
+disp("Ohms",Re,"Emitter Resistance=")
+
+// Result
+// R1=488 ohms, R2=100 ohms, Rc=400 ohms, Re=100 ohms
