FARADAY’S LAW 法拉第定律
Factors 要素Amperes 安培Time 时间
Equivalent Weight of Metal 金属当量
FARADAY’S LAW 法拉第定律One ampere flowing for one second
represents one coulomb. Faraday’ law states that 96,500 coulombs (one Faraday) will deposit one gram equivalent weight of a
metal. Equivalent weight is the atomic weight of the metal divided by it’s valence.

?1安培的电流1秒的时间通过的电量等于1库仑。
法拉第定律:1个法拉第即96,500库仑的电量可以沉积1克当量的金属。克当量是金属的原子量除以它的化合价.
