In an electrolysis experiment, the ammeter records a steady current of 1 A. The mass of copper deposited in 30 minutes is 0.66 g. Calculate the error in the ammeter reading. [ Electrochemical equivalent of copper = 0.00033 g C\(^{-1}\)]
Verified Correct Answer: .
Physical Principles & Numerical Solution
I = \(\frac{M}{zt} = \frac{0.66}{33 \times 10^{-5} \times 30 \times 60}\)
= 1.11A
Error = 1.11 - 1 = 0.11A
