When copper voltmeter is connected with a battery of emf 12 V, 2 g of copper is deposited in 30 min. If the same voltmeter is connected across a 6 V battery, then the mass of copper deposited in 45 min would be

A silver and a copper voltameter are connected in series with a 12.0 V battery of negligible resistance. It is found that 0.806g of silver is deposited in half an hour.Find (a) the mass of the copper deposited and (b) the energy supplied by the battery. ECE of silver = 1.12 xx 10^(-6) kg C^(-1) and that of copper = 6.6 xx 10^(-7) kg C^(-1)

A silver and a copper voltameter are connected in series with a 12.0 V battery of negligible internal resistance . 0.806 g of silver is deposited in half an hour in the silver voltameter. Calculate (i) magnitude of current flowing in the cicuit (ii) mass of copper deposited in the copper voltameter during the same period. Given that ECE of silver 1.12xx10^(-8) kg C^(-1)
