Homework Statement In case of having a conductor (spherically shaped and uncharged) and an irregularly shaped hole inside it with a charge at an arbitrary point, I am asked to find the electric field right outside the conductor sphere. Homework Equations Gauss's law ∫EdA=...

Thanks a lot. I tried to find the ohmic power by the following formula: P(ohmic)=R (cable) x I^2 where R is the resistance and I the current.Then I divided the value for P (ohmic) and for P (max). however the problem is that by doing this I am getting higher value for P (ohmic) than for P...

having 2 cables of 790 mm^2 cross sectional area and voltage of 450 kV. the maximum power is 700 MW and the length of cables 580 km. Assuming the resistivity of the conductor is 1.67microohmcm. then what is the ohmic lose? Thanks in advance
