Text ## Lecture (L2-2) Kirchhoff's Laws (KCL,KVL)
Kirchhoff's Laws are the first of several methods we will use to solve circuit problems. We will also use this method to DERIVE several other methods. The two basic concepts of Kirchhoff's Laws are key concepts in electrical engineering -- (1) The sum of voltages in a closed loop is zero and (2) The sum of currents coming into a node = sum of currents going out.

Application of the Day: Resistive Sensors (Technology Brief 4) Also see: Strain Gauges
Questions of the Day (Learning Objectives)
- How does current flow at branches?
- How does voltage behave around a loop?
- How do you apply Kirchhoff's Laws to solve for unknown voltages and currents in a circuit?
