Statement I: Higher the range, greater is the resistance of ammeter.
Statement II: To increase the range of ammeter, additional shunt needs to be used across it.
Explanation:
To understand the relationship between the range of an ammeter and its resistance, let's first define what an ammeter is. An ammeter is a device used to measure electric current flowing through a circuit. It is connected in series with the circuit, and the current passing through it is measured in amperes (A).
Statement I: Higher the range, greater is the resistance of ammeter.
The range of an ammeter refers to the maximum current that it can measure accurately. In other words, it is the maximum value that can be displayed on the ammeter's scale. The range of an ammeter is determined by its internal resistance. The higher the range, the larger the internal resistance of the ammeter.
Statement II: To increase the range of ammeter, additional shunt needs to be used across it.
When we want to measure a larger current than the range of the ammeter, we need to use an additional shunt resistor. The shunt resistor is connected in parallel with the ammeter, allowing a portion of the current to bypass the ammeter. By diverting some of the current through the shunt resistor, the effective current passing through the ammeter can be reduced, allowing it to measure larger currents accurately.
Explanation of the Correct Answer:
The correct answer is option 'D', which states that Statement I is false and Statement II is true.
Reason:
Statement I is false because the resistance of an ammeter does not increase with its range. In fact, the internal resistance of an ideal ammeter is supposed to be zero so that it does not affect the circuit being measured. However, in practical ammeters, there is always some internal resistance due to the resistance of the coil or the electronic components used.
Statement II is true because to increase the range of an ammeter, we need to use an additional shunt resistor. The shunt resistor is connected in parallel with the ammeter to divert a portion of the current, allowing the ammeter to measure larger currents accurately. By using a shunt resistor, the effective current passing through the ammeter is reduced, and thus, its range is increased.
Therefore, the correct answer is option 'D' - Statement I is false, and Statement II is true.
Statement II: To increase the range of ammeter, additional shunt needs to be used across it.

Therefore, the correct answer is option 'D' - Statement I is false, and Statement II is true.
