电路问题是整个电磁学的基础,因此每年高考均会涉及.除电路实验是高考的重点内容外,下面四种典型电路的分析计算也是高考考查的重点内容.一、非纯电阻电路的分析计算在非纯电阻电路的计算中,要注意非纯电阻用电器两端的电压并非是全部降落在用电器内阻上,而是只有在输出功率为零时(此时电路为纯电阻电路)两者才相等.但是,无论是在纯电阻电路还是非纯电阻电路中,发热功率都是I~2r.处理非纯电阻电
Circuit problem is the basis of the entire electromagnetics, college entrance examination will be involved each year.In addition to the circuit test is the key content of the college entrance examination, the following four kinds of typical circuit analysis and calculation is also the focus of college entrance examination test. In the calculation of non-pure resistance circuit, pay attention to the non-pure resistance of the voltage across the appliance is not all landing on the electrical resistance, but only when the output power is zero (at this time the circuit is a pure resistance circuit) both However, whether it is pure resistance circuit or non-pure resistance circuit, the heating power is I ~ 2r. Treatment of non-pure resistance
