Links to other educational sites with math/physics-related information or java applets useful for teaching: And when you get tired of learning, here is some fun stuff: Pong Simulation Circuit-level simulation of original 1972 Pong. Make a Simple Circuit For this project, you'll build a switch that allows you to control the flow of electricity. This switch can then be used in the other experiments. Materials You Will Need: Energizer® Power Pack Spring-tension wood or plastic clothespin Number 22 insulated copper bell wire (three 10" pieces with 1" of insulation stripped off both ends of all wires) Small blocks of wood One drywall nail, thumbtacks, paper clip 3-volt flashlight bulb Please Read Carefully! All experiments use safe, low-voltage battery power. Carefully follow wiring instructions for each experiment - improper wiring can result in battery leakage and/or rupture. How to Build a Switch: Wind a bare wire end around a thumbtack. Alternate: Insulated knife blade switches are available commercially, and are used to illustrate the experiments throughout this site. How to Build a Bulb Holder: Nail a clothespin to a wood block. How to Complete the Simple Circuit: When the circuit switch is open, the current does not flow to the bulb.

Simple electrical circuit with a single lamp or a motor: - Role of the generator; - connection wire; - Role of the switch. Drawing the diagram, standard symbols. Concept of the loop. Approach to the concept of a short circuit. Simple electrical circuit loop generator, switch, lamp, motor, LED, diode, connection wire, resistance (ohmic conductors), limiting itself, besides the switches to a generator and three components. Influence of the order and number of components other than the generator. Conductors and insulators. Conventional current. Series and parallel bulbs The electrical circuit comprising leads. Back to the short circuit: the distinction between short-circuit of a generator and short circuit of a lamp. Security. Current and voltage Introduction procedure of intensity and tension. Intensity : measurement, unit. Voltage : measurement, unit. Notion of branch and node. Additivity law verified for the voltage. Adaptation of a component in a given generation. Resistance
Making Boys Men: Simple Circuits for Kids Recently the boys have been showing an interest in how things work so I thought we'd test out making some simple circuits with them and whilst we were at it learn a bit about what materials conduct electricity. This is what we did.... I bought some simple electronics parts from our local Maplin store. We put 2 AA batteries in a battery box with a snap connector (this connects to the batteries and has two wires coming out of it), We then connected a wire to each side of the light bulb holder and yey, it lit up! These aren't the exact products we used, but hopefully they give you an idea of what we created if it's not clear from the pictures. Once we'd tested out the light bulb we added an extra wire so that we could test how conductive different materials are. If I'd had been a bit better prepared this would have been a great opportunity to get the boys to write down what materials they thought would or wouldn't conduct electricity. First, up we tested some Lego, which didn't work.
100 Top Resources for Electrical Engineers » Electrical Engineering Schools Electrical engineering is a highly technical pursuit that sits at the nexus of software and hardware development. Electrical engineers can design components and electronic systems for industrial machinery and consumer gadgets, and will often work in collaboration with manufacturers and designers to bring new electronic devices to market. There is also a huge hobbyist community of amateurs and professionals who advocate do-it-yourself electronics projects as a great way to learn about the inner workings of many of the household machines that people use every day. Electrical engineering can be quite technically challenging and requires a great deal of mathematics and physics knowledge, but the financial and personal rewards for succeeding in this field are great. Every piece of technology that runs on electricity, from the monster machines that clean the water for entire cities, to the ever-thinner cell phones in pockets today, required the expertise of an electrical engineer to make.
