一、电学计算题解电学计算题,就是利用串、并联电路各用电器上相应的电流、电压以及电阻之间的关系,依据欧姆定律及变形公式,用简单的数学知识求出电器(或一段线路)上未知的电学量。(一)欧姆定律通过导体(或一段线路)的电流跟导体两端的电压成正比,跟导体的电阻成反比,它是电学中的最基本的规律。任何导体(或一段线路),在任何时刻通过的电流都遵从欧姆定律。 First, the electrical calculation problem solving Electrical calculation problem, is the use of string, parallel circuit electrical appliances on the corresponding current, voltage and resistance between the relationship, according to Ohm’s law and deformation formula, using simple mathematical knowledge to find electrical (or a line ) On the unknown amount of electricity. (A) Ohm’s law through the conductor (or a line of current) with the voltage across the conductor is proportional to the resistance of the conductor is inversely proportional to, it is the most basic law in electricity. Any conductor (or a line) that passes through the current at any time follows Ohm’s law.
