## 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
