The Physics of Electricity
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 science experiment kit offers a thorough exploration of 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 119 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 motors.
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 7 kilohertz. This device safely enables the exploration of electrical phenomena such as resonance and high-pass, low-pass, and band-pass behaviours. Use the voltage and current meter to take measurements from your circuits. With this kit, the complex world of electricity becomes more tangible.
