This apparatus is used to demonstrate and teach the basic principle of an electric meter. Apparatus consists of a 3.75" (90mm) dia. air coil wound on an acrylic tube with an acrylic plate in the center to hold a compass. The coil has multiple tappings of 50, 100 and 200 turns, and also has a built-in potentiometer for varying the current, these features allow multiple readings. Operates on one "AA" battery (not included). Includes one compass. Base 7.34" (195mm) x 4.75" (120mm) x 0.5" (12mm). Total height 4.25" (110mm).
• Install a sound module to generate the sounds of police cars
• Learn the important role resistors and potentiometers
• Use a multimeter to measure invisible voltage and current
• Use a FM radio module to build an alarm clock
Tap into the awesome world of electronics with this advanced system of snap-together electric building blocks. Start out by experimenting with colorful light-up circuits as you dive into the basics of electricity. Install a sound module to generate the sounds of police cars, ambulances, or fire engines. Learn the important role resistors and potentiometers (variable resistors) play in an electronic circuit. Use a multimeter to measure invisible voltage and current flowing through your circuit. Investigate transistors in switches and amplifiers to learn how the logical circuits in computers work. Build circuits that use sensors to detect moisture, temperature, and visible light. Incorporate capacitors in your circuits to store and discharge electricity for specific functions, such as a countdown clock and a red-green alternate flasher. Test out the indispensable 555 timer to build some complicated circuits. Use an operational amplifier and an FM radio module to build an alarm clock. This kit uses the same unique electric building blocks as our other electronics kits, with the addition of many new advanced components, allowing you to build more complex circuits. The more than 140 electronic components include capacitors, resistors, transistors, LEDs (light emitting diodes), phototransistor, switches, speaker, integrated circuit, infrared LED, diodes, FM tuner, 555 timer, operation amplifier, two potentiometers, electrodes, voltage and current meter, microphone, and 9-volt battery pack.
Two plates 250mm in diameter are supported in two rigid uprights and driven by hand in opposite directions. They are heavy, high-resistance plastic with sectors of aluminum sheets. Leyden jars (condensers) made of borosilicate glass and aluminum foil store electricity until discharged by the dischargers. The whole unit is mounted on a wooden base.
Quickly removes insulation without damaging wire. Set screw adjusts stripper to fit wire gauges from 10 to 24. Made from drop-forged, heat treated steel with black baked enamel finish. PVC handles. Total length is 4 inches.
