1. Summarize the physics experiment questions in the seven examination papers of the national college entrance examination in 2004 (including the physical examination and physical examination papers), which have the following characteristics: 1. The test questions cover a wide range of topics, including the power, heat, electricity and light. Knowledge, specifically: spiral micrometer, vernier caliper reading, drawing of potential lines between parallel plates, measuring the internal resistance of the voltmeter and converting it into an ammeter, measuring the electromotive force and internal resistance of the power source, measuring the refractive index of the glass, and making electrical components Volt-ampere curve, electrical black box analysis, internal resistance of the ammeter with equivalent replacement method, free-fall motion with the tape, measurement of the luminous intensity of the light bulb, measurement of the volume of the small container using gas properties, etc. 2. Test questions focus on the experiment Examination of basic knowledge and basic skills, such as the use and reading of basic instruments, meters; basic principles and methods of experimentation
