How is the pointer scale marked?

The scale graduates from zero to infinity from the left to the right. Therefore current also graduates from zero to maximum value from left to right.

How to Calculate Value of Rh?

Value of Rh calculator uses Resistance (half)=(Resistance 1*Rm)/(Resistance 1+Rm) to calculate the Resistance (half), The Value of Rh formula is directly dependent solely on the resistance values of the current limiting resistor and the internal meter resistor. Resistance (half) and is denoted by Rh symbol.

How to calculate Value of Rh using this online calculator? To use this online calculator for Value of Rh, enter Resistance 1 (R1) and Rm (Rₘ) and hit the calculate button. Here is how the Value of Rh calculation can be explained with given input values -> 4 = (20*5)/(20+5).

FAQ

What is Value of Rh?
The Value of Rh formula is directly dependent solely on the resistance values of the current limiting resistor and the internal meter resistor and is represented as Rh=(R1*Rₘ)/(R1+Rₘ) or Resistance (half)=(Resistance 1*Rm)/(Resistance 1+Rm). Resistance 1 is the current limiting resistance in an ohmmeter and Rm is the internal resistance of the coil in PMMC instrument.
How to calculate Value of Rh?
The Value of Rh formula is directly dependent solely on the resistance values of the current limiting resistor and the internal meter resistor is calculated using Resistance (half)=(Resistance 1*Rm)/(Resistance 1+Rm). To calculate Value of Rh, you need Resistance 1 (R1) and Rm (Rₘ). With our tool, you need to enter the respective value for Resistance 1 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 Resistance (half)?
In this formula, Resistance (half) uses Resistance 1 and Rm. We can use 1 other way(s) to calculate the same, which is/are as follows -
  • Resistance (half)=Voltage*Resistance 2/(Current (fs)*Resistance 2+Current (fs)*Rm)
