Specify the points to which you could connect a voltmeter to measure the following potential differences in Figure \(21.49\): (a) the potential difference of the voltage source; (b) the potential difference across \({R_1}\) ; (c) across \({R_2}\) ; (d) across \({R_3}\) ; (e) across \({R_2}\) and \({R_3}\) . Note that there may be more than one answer to each part.
Short Answer
- Across the source the voltmeter has been drawn.
- Across the value\({R_1}\), the voltmeter has been drawn.
- Across the value\({R_2}\)and\({R_3}\), the voltmeterhas been drawn.
- Across the value\({R_2}\), the voltmeterhas been drawn.
- Across the value \({R_3}\), the voltmeterhas been drawn.
Step by step solution
Define Circuit
An electronic circuit is made up of individual electronic components including resistors, transistors, capacitors, inductors, and diodes that are linked by conductive wires or traces.
Step 2:Determining points to which we connect the voltmeter to measure the potential difference of the voltage source.
a.
The points that we connect the voltmeter to measure potential difference of the voltage source is:
Step 3:The points by we connect the voltmeter to measure the potential difference.
b.
The points to which we connect the voltmeter to measure the potential difference is across the value of \({R_1}\).
The points to connected to the voltmeter to measure the potential difference.
c.
The points to which we connect the voltmeter to measure the potential difference across the values \({R_2}\) and \({R_3}\) has been drawn.
The point connected to the voltmeter
d.
The points to which we connect the voltmeter to measure the potential difference across the value \({R_2}\) has been drawn.
The point connected across the voltmeter
e.
The points to which we connect the voltmeter to measure the potential difference across the value \({R_3}\) has been drawn.
When it’s calculated it comes \({R_1}6{\rm{ }}\Omega \).
Therefore, we get:
- The voltmeter across the source is drawn.
- The voltmeter across the value\({R_1}\), is drawn.
- The voltmeter across the value\({R_2}\)and\({R_3}\)is drawn.
- The voltmeter across the value\({R_2}\)is drawn.
- The voltmeter across the value \({R_3}\) is drawn.
