Kirchhoff's Voltage Law

Understanding Loops in a Circuit

KVL depends upon the concept of a loop. A loop is any closed path through the circuit which encounters no node more than once. Essentially, to create a loop, start at any node in the circuit and trace a path through the circuit until you get back to your original node.

Practical Resistors

Resistors are the most frequently used components in electrical circuits. Since they are so common, they are available in a wide variety of styles and manufacturing techniques. Resistors are manufactured in a variety of ways. Most commonly available commercial resistors are carbon composition or wire-wound; however, resistors on integrated circuits are generally made of semiconductor materials.

Charges and Their Motion in Materials

Electrical Basics

ll electrical principles rely on the concept of electrical charge, or simply charge. The concept of charge is based on the observation that some bodies exert non-gravitational forces on one another when they are placed close together. Like gravity, this force acts at a distance; but unlike gravity, the bodies can either attract or repel each other (gravity only attracts masses to one another).
