测量电源电动势和内电阻是电学的一个经典实验,其实验方法多样,纵观近几年全国各地的高考题,本实验是高考命题的热区域.所出命题形式源于课本,又高于课本,主要体现在要考虑电流表与电压表有一定内阻的条件下,考查对该实验原理的理解和用相关图像处理实验数据并求出电源电动势E
Measurement of electromotive force and internal resistance is a classic electrical experiment, the experimental methods are diverse, taking an overview of the college entrance examination questions all over the country in recent years, the experiment is the hot area of the college entrance examination propositions.The proposition form from the textbooks, but also higher than the textbook , Mainly reflected in the ammeter and voltmeter to consider a certain resistance conditions, test the understanding of the experimental principle and the relevant image processing experimental data and find the power electromotive force E
