Question

Explain in brief faradays 1st and 2nd law?

Answer 1

faraday's first law;-  the amount of any   substance deposited or liberated at an electrode  during  electrolysis  is directly proportion  to the amount  of  electric current  passed through the electrodes .                                            explanation ;- actually the amount of an element  discharge  during an electrolysis is directly proportional to the quantity of electricity passed through it.w directely  proportion to q w=mass of the deposit substance . q = electric charge is coloumb . faraday's second law ;-  when the same quantity of electricity is passed through  the different electolysis connected in series  the substance  deposited at the electrodes will be in  the ratio  of their  equivalent masses .                                                         explanation ;-  consider three different electrolytes  agno3, cuso4 , and al[no3]3  connected in series the same quantity of electricity  is passed through them , the weight of ag, cu ,and al  deposite on their  electrodes  will be directly proportional to their equivalent masses . equivalent masses of element =atomic mass of an element /valence of the element . accordingto faraday's , if 96,500 c [or if] electricity is passed , the masses of ag will be  108/1= 108 g  ,the masses of cu will be 63.5/2=31.75 g, the masses of a will be 27/3 =9 g respectively.

Answer 2

Faraday's Laws of Electromagnetic Induction consists of two laws. The first law describes the induction of emf in a conductor and the second law quantifies the emf produced in the conductor.
