STEP 0: Pre-Calculation Summary
Formula Used
Voltmeter Resistance = (Voltmeter Range-Current Magnitude*Resistance)/Current Magnitude
Rv = (Vr-I*R)/I
This formula uses 4 Variables
Variables Used
Voltmeter Resistance - (Measured in Ohm) - Voltmeter Resistance is the internal resistance of a voltmeter, which is designed to be very high to ensure that the meter draws minimal current from the circuit being measured.
Voltmeter Range - (Measured in Volt) - Voltmeter Range refers to the range of voltages that a voltmeter is capable of measuring. It represents the minimum and maximum voltage values that the voltmeter can accurately display.
Current Magnitude - (Measured in Ampere) - Current Magnitude is the magnitude of the rate of flow of charged particles.
Resistance - (Measured in Ohm) - Resistance is a measure of the opposition to current flow in an electrical circuit.
STEP 1: Convert Input(s) to Base Unit
Voltmeter Range: 19.32 Volt --> 19.32 Volt No Conversion Required
Current Magnitude: 2.96 Ampere --> 2.96 Ampere No Conversion Required
Resistance: 2.23 Ohm --> 2.23 Ohm No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Rv = (Vr-I*R)/I --> (19.32-2.96*2.23)/2.96
Evaluating ... ...
Rv = 4.29702702702703
STEP 3: Convert Result to Output's Unit
4.29702702702703 Ohm --> No Conversion Required
FINAL ANSWER
4.29702702702703 4.297027 Ohm <-- Voltmeter Resistance

What is basic range of a meter?

The input voltage that causes maximum deflection of the meter is known as the basic range of a meter. It occupies the lowest range on the range switch in the unamplified circuits.

How to Calculate Voltmeter Resistance?

Voltmeter Resistance calculator uses Voltmeter Resistance = (Voltmeter Range-Current Magnitude*Resistance)/Current Magnitude to calculate the Voltmeter Resistance, The Voltmeter Resistance formula is defined as internal resistance of voltmeter.Ideal voltmeter has infinite resistance so no current will flow. This is why voltmeters are placed in parallel to the circuit, not in series. Ammeter is placed in series however and has low resistance. Voltmeter Resistance is denoted by Rv symbol.

How to calculate Voltmeter Resistance using this online calculator? To use this online calculator for Voltmeter Resistance, enter Voltmeter Range (Vr), Current Magnitude (I) & Resistance (R) and hit the calculate button. Here is how the Voltmeter Resistance calculation can be explained with given input values -> 12.16865 = (19.32-2.96*2.23)/2.96.

FAQ

What is Voltmeter Resistance?
The Voltmeter Resistance formula is defined as internal resistance of voltmeter.Ideal voltmeter has infinite resistance so no current will flow. This is why voltmeters are placed in parallel to the circuit, not in series. Ammeter is placed in series however and has low resistance and is represented as Rv = (Vr-I*R)/I or Voltmeter Resistance = (Voltmeter Range-Current Magnitude*Resistance)/Current Magnitude. Voltmeter Range refers to the range of voltages that a voltmeter is capable of measuring. It represents the minimum and maximum voltage values that the voltmeter can accurately display, Current Magnitude is the magnitude of the rate of flow of charged particles & Resistance is a measure of the opposition to current flow in an electrical circuit.
