kondenzatori

cemu sluze kondenzatori kapaciteta reda velicine Farada??? vidija san u nekom katalogu od 5F, pitan profu u skoli, a on kaze da to ne postoji LOL

Za èuvanje memorije u nekim sklopovima i tako. I u na¹oj ¹koli su tvrdili da kond 1 F i V bi bilo nemoguæe napraviti je bi bio velik poput nekoliko nogometnih igrali¹ta :)

Mda fasciniraju me te profe, ja sam jos u OS svom profi iz Tehnickog! popravljao bezicnjaka sa 13-14g a to je bilo fakat davno (80-te)... Z

Da nisi tih godina posao u EMSC ? Ja sam ga zavrsio '83.

Istinaa. Nijeda se hvalim ali u nekim predmetima sam bio bolji od profesora :). Na satove radionièkih vje¾bi ( 4 h tjedno i to u jednom danu) nisam ni dolazio jer je i profesor ustvrdio da tamo nemam ¹to nauèiti (uèilo se kako izgleda otpornik i tako :). Bar u èetvrtak nisam morao u ¹kolu :P

Kondenzator od 5 F je ustvari mali akumulator. Sprijecava pad napona pri ukljucenju nekih jacih trosila i samim time cuva sklopove. Neznam tocno zadto se tako veliki koriste ,ali znam da se cesto koriste u car audiju za peglanje napona uslijed velikih struja.

I sad ima velikih kondi za dragstere i kratkotrajni boost kod Elektricnih vozila 2000 FARADA! 2.5V uredno se mogu kupiti Swiss company montena (recently merged with Maxwell). Towards the end of

2001, one of their supercapacitors reached a capacitance of 1600 Farad at a maximum voltage of 2.5 V. They store 5000 Joules or 1.4 Wh within a volume of roughly 0.3 L (5 cm diameter, 14 cm long) weighing 320 g.To store the required 220 Wh, 160 supercapacitors weighing 50 kg would suffice.With their small internal series resistance of 0.0014 Ohm,they can produce or absorb peak currents of over 300 A.Due to the excessively high currents at low voltages, operation is normally restricted to between 50% and 100% of maximum voltage and therefore,only 75% of the energy capacity is used (due to the quadratic relationship between voltage and energy content, the residual energy equates to only 25% at 50% of the voltage). This restriction and also losses in power converters result in increasing the number needed from 160 to about 250 supercapacitors, weighing nearly 100 kg, including cables and electronics.
