Overview

This is a comprehensive course on Ohm's law and Direct-Current (DC) circuits, which are circuits where the direction of the current in a circuit element does not very with time. The topics in covered in this class are: 1. Current and the Motion of Charges Definition of electric current and current densityFinding the drift velocity and density number 2. Resistance and Ohm's Law Review of Ohm's lawUnderstanding the difference between Resistance and ResistivityUnderstand the Color Code for Resistors Connection to the Electric Field 3. Energy in Electric Circuits Review of Power Rate of Potential Energy Loss Rate of Power Dissipated in a ResistorEMF's and BatteriesInternal Resistance and Maximum Power Delivered 4. Combinations of Resistors Simplifying Electric Circuits Equivalent ResistorsResistors in Series vs Parallel and how to identify the different combinations 5. Applying Kirchhoff's Rules to Circuits Problem solving strategies for single loop circuitsProblem solving strategies for multi-loop circuitsFinding the potential across resistors and between any two points in a circuitUnderstand measuring devices such as ammeters and voltmeters. 6. RC Circuits Learn how to analyze RC circuits in the short and long time limitsCharging vs discharging a CapacitorUnderstand RC time constantUnderstand energy conservation during charging and discharging a capacitor. The class is a combination of lectures and tutorial. I've put together a series of example problems, algebraic and conceptual, to help you better understand the material. The are over 60 fully solved circuit problems in this class. There are 4 problem set in the course: 1) Multiple Short Questions 2) Circuits with Resistors and EMF's 3) RC Circuits 4) Conceptual Problems If you watch the lessons, work on the problems, i'm certain you'll become very proficient at analyzing DC circuits. If at any point during any of my classes you didn't understand something, just message me and i'll make it right. Physics Ninja always has your back! Happy Learning, Dr. E.
