The formula to calculate Internal Resistance (r) is:
\[ r = \frac{L - l_2}{l_2} \cdot \Omega \]
Where:
Internal Resistance is the opposition to the flow of electric current within a conductor, measured in ohms, affecting the overall circuit performance.
Length is the distance between two points in a circuit, measured in meters, and is a fundamental parameter in electric current calculations.
Final Length is the total length of a wire or conductor in an electric circuit, including all its components and connections.
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.
Let's assume the following values:
Using the formula:
\[ r = \frac{L - l_2}{l_2} \cdot \Omega \]
Evaluating:
\[ r = \frac{1.5 - 1.2}{1.2} \cdot 50 \]
The Internal Resistance is 12.5 Ohms.
