1. The problem statement, all variables and given/known data Two hollow metal spheres (left one has radius of 0.7 meters and right one has radius of 0.4 meters) are half-submerged in the sea water with specific conductance of γ = 4 S/m. Distance between their centers is much greater than their radii dimensions and equals 60 meters. Both spheres are connected with real voltage source (U = 300V and R = 4Ω). Here's the sample image URL (please let me know if there are any troubles with this OneDrive shared link).https://email@example.com/service.svc/s/GetAttachmentThumbnail?id=AQMkADAwATNiZmYAZC1jNmNlLTE2OGMtMDACLTAwCgBGAAAD3jS4PtO4ok6emPsLe6htlgcAd9w%2BY5sSX0K4%2BOeRrODdowAAAgEMAAAAd9w%2BY5sSX0K4%2BOeRrODdowAAAIXlKJMAAAABEgAQAHmbmwDZF2QfSJuz3GK7atQD&thumbnailType=2&X-OWA-CANARY=X_OT8YKlV0CGEMSgsZMqO1DhIcR9NNQYGiGywSgDMPT37u9qjvf4GJ3S3p3X3gctYx7SfiNwtNY.&token=19efa433-21fa-4114-a44b-89c5a952a124&owa=outlook.live.com&isc=1 Question: Compute absolute value of current density at point S which lies at the exact center (30 meters from right and left sphere's center). 2. Relevant equations In the previous question I had to compute total current flow through this system. I managed to find it resistance of the sea R_sea = (1/r_left + 1/r_right) / (2πγ) which I then plugged into I = U / (R_sea + R_load). It gave me I ≅ 72.2 A. 3. The attempt at a solution I know that I = ∫JdS and J = γE, but from here on, I'm completely lost. Can somebody please help me, or at least give me a solid hint?
