Calculate electrical resistance of a uniform wire computes r_wire in ohm using the defined engineering formula and the input values provided. r_wire is expressed in ohm. No universal acceptance threshold is defined by this calculator.
Worked Example
default_test
Given:
- l_wire = 100
- a_cross = 2.5
- rho_resist = 1.72E-8
Expected Result:
- r_wire = 6.88E-7
Engineering Interpretation:
Under the given input conditions, the calculated result is: r_wire = 6.88E-7 ohm.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
Formula / Method
r_wire = rho_resist * l_wire / a_crossr_wire.
