What is ammeter?

An ammeter is an instrument used to measure the electric current in a circuit. The unit of current is the ampere (A), and ammeters are designed to measure this flow of electric charge. There are different types of ammeters, including analog and digital versions, each with specific applications and characteristics.

What is multi range Ammeter?

The basic idea of a multirange ammeter is to make the meter usable over a wide range of voltages. In order to accomplish this, each range must utilize a different shunt resistance.

How to Calculate Nth resistance in multi-range Ammeter?

Nth resistance in multi-range Ammeter calculator uses Nth Multiplier Resistance = Meter Resistance/(Nth Multiplying Factor-1) to calculate the Nth Multiplier Resistance, The Nth resistance in multi-range Ammeter formula defined as the specific resistor value that is used in the Nth range setting of the ammeter. Multi-range ammeters are designed to measure different ranges of current by incorporating multiple shunt resistors. Each resistor corresponds to a different range and is selected to allow the meter to measure currents across a wide span without damaging the instrument or losing accuracy. Nth Multiplier Resistance is denoted by R_n symbol.

How to calculate Nth resistance in multi-range Ammeter using this online calculator? To use this online calculator for Nth resistance in multi-range Ammeter, enter Meter Resistance (R_m) & Nth Multiplying Factor (m_n) and hit the calculate button. Here is how the Nth resistance in multi-range Ammeter calculation can be explained with given input values -> 7.5 = 30/(19-1).
