Answer 1

To measure potential differences in a circuit, a voltmeter can be connected at different points. (a) To measure the potential difference of the voltage source, connect the voltmeter across the terminals of the source. (b) To measure the potential difference across R₁, connect the voltmeter across the two ends of R₁. (c) To measure the potential difference across R₂, connect the voltmeter across the two ends of R₂. (d) To measure the potential difference across R₃, connect the voltmeter across the two ends of R₃. (e) To measure the potential difference across R₂ and R₃, connect the voltmeter across the two ends of the combination of R₂ and R₃.

In order to measure potential differences in a circuit, a voltmeter can be connected at different points. Here are the points to which you could connect a voltmeter to measure the following potential differences in Figure 21.47:

1. (a) To measure the potential difference of the voltage source, the voltmeter can be connected across the terminals of the voltage source.
2. (b) To measure the potential difference across R₁, the voltmeter can be connected across the two ends of R₁.
3. (c) To measure the potential difference across R₂, the voltmeter can be connected across the two ends of R₂.
4. (d) To measure the potential difference across R₃, the voltmeter can be connected across the two ends of R₃.
5. (e) To measure the potential difference across R₂ and R₃, the voltmeter can be connected across the two ends of the combination of R₂ and R₃.
