Internal Resistance using Potentiometer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Internal Resistance = (Length-Final Length)/Final Length*Final Resistance
r = (L-l₂)/l₂*Ω
This formula uses 4 Variables

Variables Used

Internal Resistance - (Measured in Ohm) - Internal Resistance is the opposition to the flow of electric current within a conductor, measured in ohms, affecting the overall circuit performance.
Length - (Measured in Meter) - Length is the distance between two points in a circuit, measured in meters, and is a fundamental parameter in electric current calculations.
Final Length - (Measured in Meter) - Final Length is the total length of a wire or conductor in an electric circuit, including all its components and connections.
Final Resistance - (Measured in Ohm) - Final Resistance is the opposition to the flow of electric current in a circuit, measured in ohms, and depends on the material and its dimensions.

STEP 1: Convert Input(s) to Base Unit

Length: 1500 Millimeter --> 1.5 Meter (Check conversion here)
Final Length: 1200 Millimeter --> 1.2 Meter (Check conversion here)
Final Resistance: 50 Ohm --> 50 Ohm No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r = (L-l₂)/l₂*Ω --> (1.5-1.2)/1.2*50

Evaluating ... ...

r = 12.5

STEP 3: Convert Result to Output's Unit

12.5 Ohm --> No Conversion Required

FINAL ANSWER

12.5 Ohm <-- Internal Resistance

What is internal resistance ?

Internal resistance is the opposition to the flow of electric current within a battery or power source itself. It causes a drop in the voltage of the power source when current flows through it, leading to a reduction in the efficiency of the device.

How to Calculate Internal Resistance using Potentiometer?

Internal Resistance using Potentiometer calculator uses Internal Resistance = (Length-Final Length)/Final Length*Final Resistance to calculate the Internal Resistance, Internal Resistance using Potentiometer formula is defined as a method to measure the internal resistance of a cell or battery using a potentiometer, which is a type of voltage divider, to determine the opposition to current flow within the cell or battery, providing an accurate measurement of its internal resistance. Internal Resistance is denoted by r symbol.

How to calculate Internal Resistance using Potentiometer using this online calculator? To use this online calculator for Internal Resistance using Potentiometer, enter Length (L), Final Length (l₂) & Final Resistance (Ω) and hit the calculate button. Here is how the Internal Resistance using Potentiometer calculation can be explained with given input values -> 12.5 = (1.5-1.2)/1.2*50.
