How many electrons flow through a metallic wire if a current of 0.5 A is passed for 2 hours? (Given 1F=96,500 C `mol^(-1)`) |
Answer» Charge flowing through the metallic wire`=Ixxt=0.5xx2xx60xx60C=3600C` But charge flowing=no. of electrons flowing `xx`charge on each electron `therefore3600=nxx1.60xx10^(-19)` or `n=(3600)/(1.60xx10^(-19))=2.25xx10^(22)`. |
