Faraday's laws definitions
Answers
Faraday's laws of electrolysis relate the amount of liberated mass at an electrode to the quantity of electricity passing through the electrode. ... Faraday's first law states that the amount of current passed through an electrode is directly proportional to the amount of material liberated from it.
Faraday's Second Law. It states that, “When the same quantity of electricity is passed through different electrolytes, the masses of different ions liberated at the electrodes are directly proportional to their chemical equivalents (Equivalent weights).” i.e., or or.
Faraday’s law of electromagnetic induction states that :
(i) When there is a change in the magnetic flux linked witht the coil , then an e.m.f is induced in the coil.
(ii) The magnitude of e.m.f induced depends directly on the rate of change of magnetic flux linked with the coil.
Observations before Faraday made these conclusions :
(i) When there is motion between coil and magnet close to it , then only there will be flow of current.
(ii) The current is increased
(a) Faster movement of the coil.
(b) Use of strong magnet.
(c) Use of larger area .
(d) Use of more turns in the coil.
The relative motion brings about change in magnetic flux which brings about an induced e.m.f
This e.m.f helps in the flow of current.
This is called electromagnetic induction.
