Graduate Electric field boundary equation implication at air/earth interface
since, B=curl(A), curl(E)= -\partialB/\partialt 1)curl(E)=- \partial/\partialt(curl(A)) 2)curl( E+\partialA/\partialt)=0 3)then since curl(\nablaV)=0, E +\partialA/\partialt =- \nablaV E= -\nablaV -\partialA/\partialtI'm confused about how to go from step 1 to step 2. The first thing I did was...- sk2nightfire
