Review6:59
Explore dependent voltage and current sources, and reinforce Ohm's law and power relations. Apply voltage-controlled and current-controlled sources with Kirchhoff's laws to analyze series and parallel circuits.
A Dependent Voltage Source Example7:12
Apply Kirchhoff's voltage law to a circuit with a dependent voltage source, use Ohm's law to find current and voltage drops, and compute the power absorbed by each component.
Power Calculations with a Dependent Voltage Source5:37
Calculate power absorption in a circuit by applying p = i^2 r to resistors, p = Δv × i to voltage sources, the dependent voltage source, and verify power balance.
Another Dependent Voltage Source Example6:07
Explore a dependent voltage source example solved with Kirchhoff's voltage law in a single-loop circuit, determining current, voltage drops across resistors, the dependent source, and power absorbed.
More Power Calculations with a Dependent Voltage Source7:07
Analyze power in a circuit with a 19.2-volt dependent voltage source driven by a 4.8-volt drop across 30 ohms; compute powers via i^2r and delta v times i, confirming balance.
Review1:09
Review of dependent sources: dependent voltage sources boost potential from negative to positive using a supply voltage calculated from elsewhere, and dependent current sources maintain current with circuit-derived supplies.

Description

Day 13 of Linear Circuits. We explore circuits with dependent sources. Again, while many engineering students are scared of dependent sources, it turns out that they behave exactly like the independent voltage sources and current sources we have seen before. It just turns out that their supply voltage (or supply current) will vary based on something else in the circuit. We have even more examples here to show you.

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