A silver and copper voltmeter are connected in parallel to a 12V battery of negligible resistance. At what rate is the energy being delivered by the battery. If in 30 minutes, 1.0 g of silver and 1.8 of copper are deposited. The electrochemical equivalents of silver = 11.2×10^−7gC−1, The electrochemical equivalents of copper = 6.6×10^−7gC^−1 [...]
