  2. Show all work for full credit in a word document or on a paper and scan your work. Save all your work as a word or a pdf file format.

I DO NOT HAVE TEXTBOOK...YOU MUST LOCATE THE PROBLEMS YOURSELF AND COMPLETE THEM

Explanation & Answer

Attached.

4-6

Solution
RT = R1+R2+R3
Putting values from figure we get
RT = 1K + 1.2K +1.8K
RT= 4KΩ
I = V/ RT
I = 24/4K = 6mA

4-8

Solution
RT = R1+R2+R3 +R4 + R5
Putting values from figure we get
RT = 22K +68K +10K+ 1M +100K
RT= 1.2 MΩ

I = V/ RT
I = 240/1.2M = 200µA

4-10

Solution
I = VT / R1+R2
I = 9/300 = 30mA

VR1 =voltage drop across R1
VR1= I X R1 = 30m X120 = 3.6V
VR2 =voltage drop across R2
VR2= I X R2 = 30m X180 = 5.4...
