Je, upinzani wa fimbo ya ardhi huhesabiwaje?

For a single vertical rod: R = ρ/(2πL) × ln(4L/d), where ρ is soil resistivity (Ω·m), L is rod length (m), and d is rod diameter (m). This formula assumes a uniform soil model.

Je, upinzani wa uuzi wa ardhi unaokubalika ni upi?

Malengo ya kawaida: <5 matumizi.

Je, fimbo zinazofanana hupunguza upinzani vipi?

Parallel rods reduce total resistance, but not proportionally due to mutual interference. For N rods spaced at distance s: R_total ≈ R_single/N × (1 + interaction factor). Rods should be spaced at least 2× rod length apart for best efficiency.

Je, thamani za kawaida za upinzani wa udongo ni zipi?

Wet clay: 10-100 Ω·m. Loam/garden soil: 50-200 Ω·m. Sand: 200-3000 Ω·m. Gravel: 3000-10000 Ω·m. Rock: 10000+ Ω·m. Soil resistivity varies greatly with moisture, temperature, and mineral content.

Je, ninapima upinzani wa udongo vipi?

Mbinu ya Wenner ya pini nne ndiyo inayotumika zaidi: pini nne zenye nafasi sawa zinachomekwa ardhini. Mkondo hupitishwa kwenye pini za nje na voltage hupimwa kati ya pini za ndani. ρ = 2πaR, ambapo a ni nafasi kati ya pini na R ni upinzani uliopimwa.
