A study potential difference of 1.62 V is maintained across two Pt electrodes placed in a solution of `CuCl_(2)` . At the end of 600s, the mass of copper deposited on the cathode is measured to be 5.92 g. The back emf of the voltameter is given to be 1.34 V. Estimate the resistance of voltameter. Faraday constant =96500 C `mol^(-1)`, relative atomic mass of copper =63.5.
