Faraday’s law of induction may be stated as follows: The induced emf ε in a coil is proportional to the negative of the rate of change of magnetic flux: B d dt ε Φ =− (10.1.3) For a coil that consists of N loops, the total induced emf would be N times as large: B d N dt ε Φ =− (10.1.4) 10-3. Combining Eqs. (10.1.3) and (10.1.1), we obtain, for a spatially uniform field B, G (cos

Cathode reaction: Cu 2+ + 2e – → Cu (s) In this case, 2 Faradays of electricity are required to deposit one mole of copper atom 63.5g. This means 2 × 96500 C liberates 63.5g of copper. Quantity of electricity passed = I×t = 4×1800C. So, if 2×96500 C liberates 63.5g, then 4×1800C will liberate = 2.4g of copper.
