This short video demonstrates an experiment to prove that a capacitor blocks direct current. Intended for beginners. [6 minutes]
Provides an overivew of computer-aided drafting and design (CADD) and its applications. Shows real-world examples of its uses including engines, circuitry, and heating and air conditioning systems. Shows...
Investigates electric-current concepts by means of discussion, laboratory work and interviews. The viewer is challenged to devise a source of potential difference from provided materials. Discusses the...
A CAL simulation exploring the relationships between signals and circuit elements. When used in conjunction with the INTERACT communication facility, it can be controlled via a World Wide Web browser and...
Uses 3-D animation and live action to explain basic electrical circuits. The properties of series, parallel, and series-parallel circuits are explained showing electrons flowing through each circuit leg in...
Explains how to use a systematic approach to locating electrical problems: know the circuit, isolate the problem, test components, fix the problem, and retest the circuit. Also discusses common problems...
Explains many of the terms associated with computers: integrated numbers, circuit, byte, bit, megabytes of memory, RAM, digital logic, binary numbers, COY, motherboard, clock speed, operating system, booting...
Demonstrates the properties of magnetic circuits with permanent magnets and pieces of soft iron. Shows how magnetic circuits can be shaped to give fields appropriate to particular devices and demonstrates...
General comparison of TTL, ECL and MOS logic gates. Review of standard TTL, low power TTL, high speed TTL, Schottky TTL, and low power Schottky TTL. Operation of a TTL gate element. Active and passive...
With a wetting balance the single phases of the dipping process are measured and plotted. Slow-motion pictures with quadruple time scale permit the observation of the different degrees of wetting. The degree...
