实验题是高考必考题型,一般分为力学实验和电学实验,“伏安法”测电源的电动势和内阻是电学实验中的重要实验之一.本文通过对2015年江苏高考题中的一道电学实验题的剖析,加强对“伏安法”测电源的电动势和内阻的理解与应用,以及实验数据的处理能力和科学精神的培养.
The test question is the entrance exam questions, generally divided into mechanical experiments and electrical experiments, “voltammetry ” measured power emf and internal resistance is one of the important experiments in electrical experiments.Through the 2015 Jiangsu college entrance examination questions Analysis of an electrical experiment, strengthen the understanding and application of the electromotive force and internal resistance of the “voltammetry” test power supply, as well as experimental data processing ability and scientific spirit training.
