What is the formula for resistivity with E (electric field)?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The formula relating resistivity to electric field is: ρ = E/J
Where:
- ρ = resistivity
- E = electric field strength (volts per meter, V/m)
- J = current density (amperes per suare meter, A/m²)
This formula shows that resistivity euals the electric field divided by the current density, providing another way to understand how materials resist current flow.
