Human power generation 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.
Two different metals in contact with each other in their electric potential difference generated between. Its value depends on the nature of the metal and the contact surface temperature. For different work function metals (the electron emitting surface of the desired metal work) arising from the difference.
Contact potential difference generated due to:
1, the electron work function of the two metals are different;
2, the electron density of the two metals are different.
Several metals are sequentially connected, the contact potential difference at both ends only with the nature of the metal, regardless of the intermediate metal.
Different metals potential difference between:
K, Ga, Na, Me, Al, Zn, Fe, Sn, Pb, H, Cu, Hg, Ag, Pt, Au, with serial, the left is a negative electrode.
The experimental device, respectively, using the rod, rod, galvanized rods as the experimental contrast material, the use of human palm skin temperature and body fluids, the formation of metal galvanic cell experiments contrast.
