Review2:17
Review ohm's law with delta v from positive to negative, relate current to ir, and summarize power (absorbed or generated), voltage sources, current sources, and kcl/kvl in linear circuits.
Review: KCL and a Water Analogy4:19
Explore Kirchhoff's current law through a water analogy, showing that what flows into a node must flow out. Practice balancing currents at nodes with given in and out values.
Review: KVL and a Water Analogy2:31
Use a water analogy to visualize Kirchhoff's voltage law, with ground at zero volts, voltage sources boosting to 12 and 15 volts, and current returning to zero through resistors.
Review: KVL and a Water Analogy - Part 23:41
Explore Kirchhoff's voltage law using a water analogy to map node potentials, identify Delta V across the resistor, and show ground choice does not affect the circuit's result.
An Example Using Ohm's Law, KCL, and KVL to Find Unknown Voltages and Currents8:27
Use ohm's law, kcl, and kvl to determine I_x and the voltage across the current source by tracing node voltages and resistor drops in the 60-volt circuit.
An Example that Shows You How to Start When You Don't Know Anything8:48
Start from a 3 V source with three resistors, name currents I1, I5, and I10, apply Ohm's law and kcl to form four equations, solve by substitution, and verify.
Review0:46
Revisit Ohm's law, Kirchhoff's current law, and Kirchhoff's voltage law to unlock powerful tools for basic circuit analysis.

Description

Day 6 of Linear Circuits. After a quick review of Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL) more examples are presented. It turns out, you can solve lots and lots and lots of linear circuits just using KCL, KVL and Ohm's Law. : )

The material covers all of the lecture material from a sixth lecture in a traditional, sophomore-level linear circuits class.
