| |
joule's law |
heat developed in a conductor is directly proportional to resistance of conductor, square of current and time the current is maintained |
| |

| |
coulombmeter |
measures number of coulombs of electric charge |
| |
spontaneous reaction |
involves the transfer of electrons from one reactant to the other |
| |
electroplating |
electrolytic deposition of one metal on the surface of another |
| |
Faraday's First Law |
mass of an element deposited or liberated during electrolysis is proportional to the quantity of charge that passes |
| |
Faraday's Second Law |
mass of an element deposited or liberated during electrolysis is proportional to the chemical equivalent of the element |
| |
