I recently started my study on electric flux and gauss's law in college, and I am currently really confused. So, I may ask some really stupid questions, please forgive me on that.
I don't understand how we could use electric flux to calculate the Electric Field.
Say we have a spherical surface with a whatever charge OUTSIDE that surface. Electric flux of that closed surface is Zero. However, what confuses me comes next. If the electric flux is zero, according to gauss's law and the formula ∮E⋅dS(Since it's a spherical surface, Flux = E*A), can I then conclude the electric field is ZERO?
What is that "electric field" calculated in this case? Why is it zero even though there is a charge out there?
Also, if I divide Flux by Area, I got a value of electric field? Is that the electric field for an area? Shouldn't electric field be described at a certain point?
