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.

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).

Project 1: Resistors
Use the Analog Discovery™ and a digital multimeter to explore a fundamental equation used in electric circuit analysis and design: Ohm's Law.

Project 2: Resistors
Apply a time-varying voltage to a resistor using the Analog Discovery™ waveform generator. We will use the Analog Discovery oscilloscope to measure the resulting current, and plot the voltage as a function of current. The resulting plot will show the resistor's voltage-current characteristic, or I-V curve.

Project 3: Resistors
When resistors are connected in series, the combination has an equivalent resistance that is the sum of the resistances of the individual resistors. This property can be useful in creating desired resistance values from a limited selection of fixed resistors. The user will create a 9 kΩ resistor from the resistors available in the Digilent's® Analog Parts Kit.

If the total voltage difference across a set of series resistors is known, the voltage differences across any individual resistor can be determined by the concept of voltage division.

In any electric circuit, our typical goal is to move charges around to perform some useful task. This involves both voltage differences and currents. We create voltage differences in the circuit, which provides energy differences (or electromotive forces) which move charges around, creating currents.
