Identify the circuit (Figure 12.3) in which the electrical components have been properly connected.
(a) (i)
(b) (ii)
(c) (iii)
(d) (iv)
Hence, the correct answer is option (b)
Explanation:-
Essential conditions are necessary when electrical components are connected
1) In a circuit ammeter should be connected in series.
2) In a circuit voltmeter should be connected in parallel
3) Positive terminal of Voltmeter and Ammeter should be connected to the positive terminal of battery. Same
goes with negative terminal. All three conditions are valid only in circuit diagram 2.
