- R
- V
- I
- P
Hint:
Resistance depends on the cross-sectional area, length, and resistivity of the conductor.
The correct answer is: R
- is used for calculating resistance of the conductor.
- Resistance is the opposition faced by the flow of electric current in a circuit.
- Here, = resistivity of the conductor ; l= length of the conductor ; A = cross-sectional area.
