## Homework Statement

Calculate V

_{1}, i

_{1}, V

_{2}, and i

_{2}in http://images3a.snapfish.com/232323232fp733;4>nu=52::>379>256>WSNRCG=3357955356347nu0mrj"

## 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. R

_{1}and R

_{2}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 i

_{0}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 V

_{1}3*4=12 yes?

Is it necessary to combine any of the resistors to finish the problem? Also because there is no element where i

_{1}is, would this mean there is no current usage and i

_{1}is zero?

Thanks for any help in advance
