What is PMMC?

PMMC stands for Permanent Magnet Moving Coil. The instruments which use the permanent magnet for creating the stationary magnetic field between which the coil moves are known as a permanent magnet moving coil or PMMC instruments.

What is multi range voltmeter?

The basic idea of a multi-range voltmeter is to make the meter usable over a wide range of voltages. In order to accomplish this, each range must utilize a different series resistance.

How to Calculate nth resistance in multi-range voltmeter?

nth resistance in multi-range voltmeter calculator uses nth resistance=(nth m-(n-1)th m)*Rm to calculate the nth resistance, The nth resistance in multi-range voltmeter calculates the value of Rₙ for its specified mₙ, used for range extension. nth resistance and is denoted by Rₙ symbol.

How to calculate nth resistance in multi-range voltmeter using this online calculator? To use this online calculator for nth resistance in multi-range voltmeter, enter nth m (mₙ), (n-1)th m (mₙ₋₁) and Rm (Rₘ) and hit the calculate button.

FAQ

What is nth resistance in multi-range voltmeter?
The nth resistance in multi-range voltmeter calculates the value of Rₙ for its specified mₙ, used for range extension and is represented as Rₙ=(mₙ-mₙ₋₁)*Rₘ or nth resistance=(nth m-(n-1)th m)*Rm. nth m is the multiplying power of coil associated with the nth resistor in multi range ammeter, (n-1)th m gives the value of multiplying power that is effective for the (n-1)th resistance in series and Rm is the value of the Ayrton shunt.
How to calculate nth resistance in multi-range voltmeter?
The nth resistance in multi-range voltmeter calculates the value of Rₙ for its specified mₙ, used for range extension is calculated using nth resistance=(nth m-(n-1)th m)*Rm. To calculate nth resistance in multi-range voltmeter, you need nth m (mₙ), (n-1)th m (mₙ₋₁) and Rm (Rₘ). With our tool, you need to enter the respective value for nth m, (n-1)th m and Rm and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate nth resistance?
In this formula, nth resistance uses nth m, (n-1)th m and Rm. We can use 2 other way(s) to calculate the same, which is/are as follows -
  • nth resistance=Rm/(nth m-1)
  • nth resistance=(Rsh1+Rm)/nth m
