An electrolytic cell containing a solution of CuSO_(4) has an internal resistance of 1Omega. It is connected in series with 3 V battery of negligible resistance and a 4Omega resistance. The mass of copper which will be deposited on the copper electrode in 30 min is calculated. If 4 Omega resistance is connected in parallel across the electrolytic cell and the same battery is used, the amount of copper deposited in 30 min is calculated ECE of Cu= 0.00033 g/C. Using Faraday's first law of electrolysis, the mass deposited on the copper electrode can be calculated. For series connection of 4 Omega resistor, the current flowing through electrolyte is
