高考对电场内容的考查主要集中在场强、电势能与静电力做功、带电粒子在电场中的运动、电容器等知识点上,试题对电场知识的单独考查,以选择题为主,难度不大;电场知识与牛顿运动定律、动能定理、功能关系相结合的综合考查,以计算题为主,难度较大.高考重点在带电粒子在电场中的运动,带电粒子在电场、磁场形成的复合场中的运动仍可能是压轴题.一、电场强度
College entrance examination of the electric field content mainly concentrated in the field strength, potential energy and electrostatic power work, charged particles in the electric field in the movement, capacitors and other knowledge points, the test questions on the electric field knowledge alone to multiple choice, the difficulty is not big ; Electric field knowledge and Newton’s law of motion, kinetic energy theorem, the functional relationship of a combination of comprehensive examination, to calculate the problem-based, more difficult.Calculation of charged particles in the electric field movement, the charged particles in the electric field, the magnetic field formed by the composite field The movement may still be a finale question. First, the electric field strength
