Kirchhoff's Law
-are two equalities that deal with the current and voltage in the lumped element model of electric circuits.
-first describe in 1845 by Gustav Kirchhoff.
Kirchhoff's Current Law (KCL)
-The summation of current(I) entering a node is equal to the summation of current(I) leaving the node.
Kirchhoff's Voltage Law (KVL)
-The sum of voltages around a loop is zero(0).
Important terms to remember:
- Branch-represents a single element.
- Nodes-the meeting point between two or more branches.
1. Reference
2. Non-reference
- Loop-any closed loop path in the circuit.

Reflection:
I was able to learn how to construct an equation using kirchhoff's law with ohm's law. In kirchhoff's voltage law, it doesn't matter whether you use counter-clockwise or clockwise as basis for creating an equation. As long as you are consistent with what you are going to use in order to avoid confusion.
