Explanation / Answer

Given

R1 = 8.2 k, R2 = 1.6 k, VCC = 10 V, RC = 1 k, RE = 300 , and dc = 150.

Note: The transistor is silicon.

A) Base voltage VB =  V = IR = 1 A* 8.2 = 8.2 V

( Assumed I =1 A)

Emitter voltage VB =  V = IR = 1 A* 1.6 = 1.6 V

( Assumed I =1 A)

b) IC = VCC / RCC = 10/ 1000 = 1/100 = 0.01 A

c)

Collector voltage VC =  V = 0.01 * 8.2 = 0.082

Collector-emitter voltage VCE =  V = 0.01 * 1.6 = 0.016

Cutoff collector-emitter voltage VCE(off) =  V. = total = 0.098
