Start where?????
Solve what we can.
R2 =

R3 = 2Ω
V3= 0.5 V
I3= .25 A
R4 = 4Ω
V4=
I4 =
V1= I1 R1 14= I1 (7)
I1 = 2 amps Can I give this
to anything
kinda
else?
R5 = 1 Ω V5= 1.25 V I5= 1.25 amps It’s the total current
for the
entire other group
R6 =
V6=
I6= 1.25 amps
Now what?????

Can I give this to anything else?
Yup (R2)
V5= I5 R5 3.75= I5 (3)
I5 = 1.25 amps
Can I give this to anything else?
Yup (R6)
R1 = 7Ω
V1= 14 V
I1 =

What is the total
current in the circuit?
2 amps
How much
R2 =
V2= 0.5 V I2=
R3 = 2Ω
V3= 0.5 V
I3= .25 A
R4 = 4Ω
V4= 3 V
I4= 0.75 amps
R5 = 1 Ω
V5= 1.25 V I5= 1.25 amps
R6 =
V6=
1.25 amps went down at
1st the branch?
So . . How much went
up? 0.75 amps

THINK !!!!!!
What is the total

current that went up
at the 1st branch?
R3 = 2Ω V3= 0.5 V I3= .25 A
0.75 amps How much of
R4 = 4Ω V4= 3 V
I4= 0.75 amps
that went
0.25 amps down at the
R5 = 1 Ω V5= 1.25 V I5= 1.25 amps
2nd branch?
R6 =

What is the total

I3= .25 A
What must be
I4= 0.75 amps 3.5 V
the total
voltage for the
