Resistance (Current electricity)
R = ρL/A
Where: A = area (m²) / amplitude, L = length (m) / angular momentum / inductance, R = range / radius / resistance, ρ = density (kg/m³) / resistivity
Solved example
Given: A = 7, L = 5, rho = 10
Find: R (range / radius / resistance)
- Formula: R = L·ρ/A
- Substitute the values: R = 10·5/7
- Result: R = 7.142857 Ω
Answer: R = 7.142857 Ω
