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)

An ammeter and a voltmeter are connected in series to an ideal battery of emf E. If the ammeter reads I and voltmeter reading V, then

50 Omega and 100 Omega resistors are connected in series. This connection is connected with a battery of 2.4 volts. When a voltmeter of 100 Omega resistance is connected across 100 Omega resistor, then the reading of the voltmeter will be
