The correct answer is: A. multiple shunt or series resistances inside the meter.
A multirange instrument is an electrical measuring instrument that can be used to measure a variety of different electrical quantities. It does this by having multiple ranges, each of which is designed to measure a different range of values. The ranges are typically selected by switching between different shunt or series resistances.
Shunt resistances are used to reduce the current that flows through the meter when measuring high values. Series resistances are used to increase the current that flows through the meter when measuring low values.
Multirange instruments are typically used in applications where it is necessary to measure a variety of different electrical quantities. For example, they are often used in test and measurement equipment, power supplies, and industrial control systems.
Here is a brief explanation of each option:
- Option A: multiple shunt or series resistances inside the meter. This is the correct answer. As explained above, shunt and series resistances are used to select different ranges in a multirange instrument.
- Option B: multicoii arrangement. This is not the correct answer. A multicoil arrangement is used in some types of meters, but it is not used in multirange instruments.
- Option C: variable turns of coil. This is not the correct answer. Variable turns of coil are used in some types of meters, but they are not used in multirange instruments.
- Option D: multi range meters inside the measurement system. This is not the correct answer. A multirange meter is a single instrument that can be used to measure a variety of different electrical quantities. It does not have multiple meters inside it.
- Option E: any of the above. This is not the correct answer. Only option A is correct.
