Electric shunt - QuickField simulation example
Engineering question
How to calculate the voltage drop V in the electric shunt?
Answer
Apply the known current with one terminal grounded and read the potential of the other terminal; the terminal potential gives the shunt voltage drop.
Typical applications
precision current shunts, DC current sensors, calibration shunt resistors

Simulation problem
Problem Type3D problem of DC conduction.
Geometry
Given
Electric conductivity of metal σ = 56 MS/m;
Electric current I = 100 A.
Task
Calculate the voltage drop V in the electric shunt.
