LC of ammeter = 0.2/10 a = A = 0.02 A
LC of Voltmeter = 1/10 = 0.1 V
Current = 15 x 0.02 A = 0.3 A
Potential difference = 21 x 0.1 V = 2.1 V

Given Information:
- The ammeter reading is 0.4 A.
- The voltmeter reading is 3.2 V.
Calculating the Least Count of the Voltmeter:
The least count of a voltmeter is the smallest change in voltage that it can measure. To calculate the least count, we need to know the full-scale voltage range of the voltmeter.
Let's assume that the full-scale range of the voltmeter is 10 V.
The least count of the voltmeter can be calculated using the formula:
Least Count = Full-scale range / Number of divisions
Assuming that the voltmeter has 100 divisions, we can calculate the least count as follows:
Least Count = 10 V / 100 divisions
Least Count = 0.1 V/division
Therefore, the least count of the voltmeter is 0.1 V.
Calculating the Least Count of the Ammeter:
The least count of an ammeter is the smallest change in current that it can measure. To calculate the least count, we need to know the full-scale current range of the ammeter.
Let's assume that the full-scale range of the ammeter is 1 A.
The least count of the ammeter can be calculated using the formula:
Least Count = Full-scale range / Number of divisions
Assuming that the ammeter has 100 divisions, we can calculate the least count as follows:
Least Count = 1 A / 100 divisions
Least Count = 0.01 A/division
Therefore, the least count of the ammeter is 0.01 A.
Calculating the Voltage and Current across the Resistor:
The potential difference developed across the ends of the resistor is given by the voltmeter reading, which is 3.2 V.
The current flowing through the resistor is given by the ammeter reading, which is 0.4 A.
Therefore, the voltage across the resistor is 3.2 V and the current through the resistor is 0.4 A.
Explanation:
- The ammeter reading of 0.4 A indicates the current flowing through the resistor.
- The voltmeter reading of 3.2 V indicates the potential difference developed across the ends of the resistor.
- The least count of the voltmeter is 0.1 V, which means it can measure voltage changes in increments of 0.1 V.
- The least count of the ammeter is 0.01 A, which means it can measure current changes in increments of 0.01 A.
- The voltage across the resistor is 3.2 V and the current through the resistor is 0.4 A.
- The ammeter reading is 0.4 A.
- The voltmeter reading is 3.2 V.
