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 voltmeter is connected across a battery of emf 12 V and internal resistance of 10 Q. If the voltmeter resistance is 230 Q, what reading will be shown by voltmeter?

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)
