Current Electricity and Electrical InstrumentHard
Question
The electro-chemical equivalent of a substance is numerically equal to the mass of the substance deposited if a current I flows through the electrolyte fro 0.25 seconds. the value of I is :
Options
A.1A
B.2A
C.3A
D.4A
Solution
We have, m = Zq
or Z =
For q = 1C, Z= m
So, for 1coulmb of charge, q = i t or 1 = i × 0.25 i = 4A
or Z =
For q = 1C, Z= m
So, for 1coulmb of charge, q = i t or 1 = i × 0.25 i = 4A
