23-1 What Is Physics? In this chapter we will introduce the following new concepts: The flux (symbol Φ ) of the electric field. We will then apply Gauss’ law and determine the electric field. We will also apply Gauss’ law to determine the electric field inside and outside charged conductors. 彰化師大教學卓越－普物教材－理學院長郭艷光主持
