Thames and Kosmos Electricity Master Lab
We encounter electricity everywhere in our lives - at home, in school, even our bodies have electric charges in them. Alternating current (AC), or electric current that cyclically changes its direction, plays a particularly important role in our world. Countless 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 (DC), the unidirectional current from standard batteries. With this kit, you can safely experiment with the physical science theories and applications of electricity. Conduct 110 experiments to investigate electrical engineering from AC to DC. Start by exploring the basics of electric current by building simple circuits with batteries, switches and lights. Build series and parallel circuits as well as more complex circuits such as a traffic signal and alarm system. Experiment 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. Operate an electromagnetic coil, capacitor and transformer in an AC circuit and examine their behaviours 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 about 10 kilohertz. This device safely enables the exploration of electrical phenomena such as resonance and high-pass, low-pass and band-pass behaviours. Measure frequencies with the electromechanical frequency meter. The plug-together electric building blocks make circuit assembly quick and easy. A 96-page, full-colour manual provides illustrated assembly instructions.
