Foundations of Electric Current and DC Circuits

Understanding how electric current behaves in direct current (DC) circuits is the foundation of modern electronics and electrical engineering. This text-based course guides you from the fundamental definitions of charge and current to solving complex resistor and cell networks with confidence. What you'll learn: - Understand the core concepts of electric current, electromotive force (EMF), and terminal voltage - Analyze the internal resistance of cells and how to combine them in series and parallel configurations - Apply Kirchhoff's current and voltage laws to systematically solve complex circuit loops - Master the principles and practical applications of the Wheatstone bridge and the meter bridge - Explore modern DC circuit applications including basic battery management concepts - Practice solving circuit analysis problems step-by-step through written scenarios The course begins with essential terminology and the physical principles of charge flow, establishing a strong foundation before introducing network theorems and measurement instruments. This course is designed for beginners, physics students, and aspiring engineers looking for a solid, conceptual understanding of DC circuit analysis with no prior advanced engineering background required.
