Human Body Conductivity
Operation: Place both hands on the electrodes respectively, and see if the light turns on? Function Overview: The exhibit consists of two electrodes, a low-voltage power supply, and an LED strip. Visitors place their hands on the electrodes respectively, connecting themselves into the circuit. At this point, the light bulb will turn on because the circuit is completed, demonstrating that the human body is a conductor. Scientific Principle: The human body can conduct electricity because it contains various trace elements such as calcium, sodium, and potassium. Additionally, human skin sweat contains a large amount of water, and water contains numerous electrolytes. This exhibit uses the human hands as electrolytes to generate current, allowing observation of the light's brightness. This demonstrates that the human body is a conductor, and safety precautions with electricity are important in daily life.
