Identify the circuit (Figure 12.3) in which the electrical components have been properly connected.

Circuit shown in figure (ii) is properly connected. In other figures, the connections are not correct. For e×ample: in figure (i), voltmeter is connected in series and not in parallel. Similarly in figure (iii), ammeter is in parallel which should be in series. In figure (iv), the negative terminal of battery has been connected to positive terminal of ammeter whereas it should be connected to negative terminal and not positive terminal of ammeter.
