# Kirchhoff and Potentials question.

 HW Helper P: 2,616 KVL = Kirchoff's voltage law KCL = Kirchoff's current law You need to write an equation for the current flowing out and into each and every node. For example, the current flowing from Va to Vb across the 6k resistor is given by $$\frac{V_a - V_b}{6k}$$; current from Vb to Va in the opposite direction along the same path is given by $$-\frac{V_a - V_b}{6k}$$.
