Function fusing_current 

pub fn fusing_current(
    area_circular_mils: f64,
    time_s: f64,
    ambient_c: f64,
    melting_temp_c: f64,
) -> Result<f64, CalcError>

Calculate fusing current from cross-sectional area using Onderdonk’s equation.

I = A_circ × √( log₁₀(1 + (Tm − Ta) / (234 + Ta)) / (33 × t) )

Arguments

• area_circular_mils — conductor cross-section in circular mils (must be > 0)
• time_s — pulse duration in seconds (must be > 0)
• ambient_c — ambient temperature in °C
• melting_temp_c — melting temperature of conductor in °C (must be > ambient_c)

Errors

Returns CalcError::OutOfRange if inputs are invalid.
