We encounter electricity everywhere in our lives: at home, in school, even our bodies have electric charges in them. Alternating current, known as AC, or an electric current that cyclically changes its direction, plays a particularly important role in our world; ountless appliances and devices, including televisions, electric heaters, desk lamps, and smartphone transformers are operated with AC.
This is the first science experiment kit to thoroughly explore alternating current in addition to the more commonly addressed direct current or DC, the unidirectional current from standard batteries. With this kit, you can safely experiment with the physical science theories/applications of electricity. Conduct 119 experiments to investigate electrical engineering from AC to DC. Begin by exploring the basics of electric current by building simple circuits with batteries, switches, and lights, and build series and parallel circuits as well as more complex circuits such as a traffic signal and alarm system.
Experiment in order to observe the physical effects of electric current such as heat and magnetism, discover electrochemistry by building a lemon battery, play around with permanent magnets and electromagnets to learn about magnetism and its applications, such as relays and solenoid brakes, and operate an electromagnetic coil, capacitor, and transformer in an AC circuit and examine their behaviors at different frequencies. A special AC generator creates a harmless AC current with a variable frequency, from a few hertz (or cycles per second) to around about 10 kilohertz. This device enables the safe exploration of electrical phenomena such as resonance and high-pass, low-pass, and band-pass behaviors. You can also measure frequencies with the electromechanical frequency meter.
Plug-together electric building blocks make circuit assembly quick and easy and a 128-page, full-color manual provides illustrated assembly instructions.
