Homework Statement
Find the equivalent resistance seen by the source and use the result to find i, i1, and v.
Homework Equations
V=IR
for series circuits:
RT=R1+R2+...+Rn
VT=V1+V2+...+Vn
for parallel circuits:
IT=I1+I2+...+In
1/RT=(1/R1+1/R2+...+1/Rn)
The Attempt at a Solution
since 30Ω and 6Ω are parallel,
1/R=(1/6+1/30)=1/5
R=5
R=5Ω and 3Ω are series, so:
RT=5+3
RT=8Ω
i solved for the i using this:
i=V/R1=48/3
i=16 A
in getting the total current, i did two things. is this the right thing to do?
IT=V/RT=48/8
IT=9.6 A
or this?
IT=VT/RT=(48+v)/8
however, i don't know how to get v there.
or are both of them wrong? help! I'm new to this that's why I'm still a little confused. thank you very much.
