ACTIVITY Return stack mount the following sequence: a copper plate, felt (fabric measuring 10 cm x 2 cm) soaked with the solution of copper sulfate (CuSO - 6.5g of salt in 25ml of water); cardboard measuring 10 cm x 2 cm soaked with saturated salt (NaCl), felt soaked in the solution table salt, a plate of zinc. Repeating the same sequence twice. Connect the wire to a lamp and to the plates (copper and zinc). Observe, record and compare the effect obtained with the other experiments. In a similar experiment, Volta proved that the muscle contractions was caused by contact between the two metals. The various materials present in our day-to-day permit to build many cells, taking advantage of the power generated to run some objects like clock, calculator, flashlight, toys. What is the relationship between the battery and the strange sen sation (shock) caused by aluminum foil? You know you can have a stack, similar to these, inside the mouth? You built cells that rapidly diminished its potential, as the quantities of substances consumed. The light intensity of the lamp was decreasing until fade. You certainly know heaps of various sizes with the same indications: positive (higher potential) and negative (lower potential), the voltage printed 1.5 V. This ddp between the poles is maintained by chemical reactions that occur within cells. The shock in the tooth sealed by amalgam causes a feeling of "tingling" because the voltage is low.

AKTIVNOST Vratiti stog montirati sljedeću sekvencu: bakrena pločica, pusta (tkanina dimenzije 10 cm x 2 cm) natopljena otopinom bakar sulfat (CuSO - 6.5g soli u 25ml vode); kartona dimenzija 10 cm x 2 cm natopljene zasićenom soli (NaCl), osjetio natopljenom u otopini soli stol, tanjur od cinka. Ponavljanje isti slijed dva puta. Spojeno na lampe i ploče (bakar i cink). Promatrajte, snimiti i usporediti učinak postignuto s drugim pokusima. U sličnom eksperimentu, Volta pokazao da su kontrakcije mišića uzrokovana kontakta između dva metala. Razne materijale prisutan u našem dana u dan dozvolu za izgradnju mnoge stanice, iskorištavanjem energije proizvedene pokrenuti neke predmete kao što su sat, kalkulator, baterija, igračke. Kakav je odnos između baterije i čudno sen Sation (šok) uzrokovane aluminijske folije? Vi znate da možete imati hrpu, nalik na njih, u ustima? Vi izgrađena stanica koje se ubrzano smanjuje svoj potencijal, jer su količine tvari konzumira. Intenzitet svjetla od svjetiljke smanjivala do blijede. Vi sigurno znate hrpe različitih veličina s istim indikacijama: pozitivne (veći potencijal) i negativne (niži potencijalni), tiskane napon 1,5 V. Ovo DDP između polova se održava kemijske reakcije koje se odvijaju u stanicama. Šok u zubu zapečaćuje amalgama izaziva osjećaj "trnci", jer je napon je nizak. Umjetna Electric Organ
