3D problem of DC conduction.
Electric conductivity of metal γ = 56e6 S/m;
Electric current I = 100 A.
Calculate the voltage drop in the electric shunt.
One of the terminals is grounded. The task is to find the electric potential of the second terminal with known electric current.
Potential difference between the terminals is 2.1 mV.
Current density distribution in the electric shunt is shown below.
