What it calculates
The “Lightning rod height” calculator computes Lightning rod height in m from 2 parameters: object height, m, protection radius at h_x, m.
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters Object height, m = 5, Protection radius at h_x, m = 5 the result is 8.77 m (h ≈ (r_x + 1.63·h_x) / 1.5).
