Kirchhoff's voltage law:
From Ohm's law:
, where I is current and R is resistance.
Let's label the different regions in the diagram as shown below:
Consider loop 1 in a clockwise direction:
9 - 6I1 - 12I3 = 0
How much current flows through the bottom wire in the figure(Figure 1) ?
Express your answer to two significant figures and include the appropriate units.
In which direction current flows through the bottom wire in the figure?
