Applying Kirchhoff’s Rules to circuits written in electronics style is straightforward.

(a) Find the nodes, places where three or more wires join.
(b) Assign a current, including direction, to each branch.
(c) At each node, currents in must equal currents out.
(d) The voltage drop from battery to ground equals the drop over resistors and LEDs.
Note that if the current is in the opposite direction, you need a minus sign.

I don't really get your question.. what is it that you don't understand?

anonymous · Answer

I need to find the current in each branch.

anonymous · Answer

I mean I need to find the equation of current in each branch. http://postimage.org/image/503pbju7v/
