Question
What does 'ρ' represent in this equation?
- Resistivity
- Length
- Cross-section
- Shape
Hint:
rho 'ρ' is derived from the Greek word.
The correct answer is: Resistivity
- Resistivity is the resistance of a conductor across a unit cross-sectional area per length.
- It is denoted with the Greek letter 'rho' 'ρ'.
