Conductive body experimental apparatus ,This is our new creative series which used for junior middle school Innovation experimental ! new beautiful design and very eash to be used.
Human tissue contains large amounts of water, minerals, electrolytes, etc., so the body is a conductor, the human body but also with the conductivity level of the degree of wet and dry skin, rough and dry skin resistance of up to tens of ohms, tender and moist skin, can be reduced to 800 ohm resistor, and the voltage level of the body's electrical conductivity and resistance of the human body, the human body to endure short time current is about 30mA or less, the general current of 1mA about human perception, a few seconds will cause life-threatening.
Within the experimental device amplifier. Conductive balls because potential difference is present across, when two metals in contact with both hands, the touch point, the minute amount of current through the body, through the amplifier circuit drives the light emitting diode and to send music musical sound IC module.
