(The symbol on the bottom right is a "ground". Since there's only one ground, current won't flow through it, but it acts as a reference point for zero potential.)

To analyze this circuit, use Ohm's Law:

$\overline{){\mathbit{V}}{\mathbf{=}}{\mathbit{i}}{\mathbit{R}}}$

And Kirchhoff's Loop Rule:

$\overline{){\mathbf{\sum }}{\mathbit{V}}{\mathbf{=}}{\mathbf{0}}}$

Assume current runs clockwise.
