Electrical Resistivity Calculator

Material’s resistance to electric current flow.The formula is given by:

Where:

• $\rho$ is the electrical resistivity (in ohm-meters, Ω⋅m),
• $R$ is the electrical resistance (in ohms, Ω),
• $A$ is the cross-sectional area of the material through which the current flows (in square meters, m²),
• $L$ is the length of the material through which the current flows (in meters, m).
