Homework Statement
Calculate V1, i1, V2, and i2 in http://images3a.snapfish.com/232323232%7Ffp733%3B4%3Enu%3D52%3A%3A%3E379%3E256%3EWSNRCG%3D3357955356347nu0mrj"
Homework Equations
Kirchhoff's Voltage Law (KVL) - The algebraic sum of voltages on a closed loop are equal to zero.
Kirchhoff's Current Law (KCL) - The algebraic sum of currents entering a node (or closed boundary) is zero.
Ohm's Law - V = IR, where V is voltage, I is current and R is resistance.
Various other things like how to add resistors in parallel and series to make a circuit simpler to understand. e.g. R1 and R2 in series are equal to
[tex] R_{eq}= R_{1}+R_{2} [/tex]
in parallel on the other hand
[tex] \frac {1}{R_{eq}}=\frac {1}{R_{1}}+\frac{1}{R_{2}} [/tex]
The Attempt at a Solution
So this is our first homework assignment and I am just looking for some guidance here. In the figure I linked to I labeled i0 so that I could easily reference it. This should be equal to 12/4 which is 3 amps correct? and
[tex] i_{0}=i_{1}+i_{2} [/tex]
yes? That would also make V1 3*4=12 yes?
Is it necessary to combine any of the resistors to finish the problem? Also because there is no element where i1 is, would this mean there is no current usage and i1 is zero?
Thanks for any help in advance
