Identify the circuit (Figure 12.3) in which the electrical components have been properly connected.
(a) (i)
(b) (ii)
(c) (iii)
(d) (iv)

Solution: The answer is (b) (ii)

Explanation:

For current to flow, an electrical circuit must be closed. An open circuit can result from improperly connected components.

An ammeter measures the current in a circuit. It has a low resistance to allow current to flow through it. The ammeter is always in series because the current is the same. The ammeter’s positive terminal connects to the battery’s positive while the negative connects to the other side.

A voltmeter measures the potential difference between two points in a circuit. The voltmeter has a high resistance and is connected in parallel to the points where the potential is to be measured.

The correct circuit has an ammeter in series with a voltmeter parallel to the resistor, with the ammeter’s positive terminal to the resistor and its negative terminal to the other end.

So the correct answer is (B).
