电路的计算在中学教学中非常重要,所以它一直是初中物理教学中的重要内容,也是中考重点内容。由于这类问题比较复杂,所以也一直是教学的难点。电路计算所涉及的物理量比较多,包括电流、电压、电阻、电功、电功率等,而且它们的关系复杂,但也有规律可循,只要灵活运用这些规律,有? The calculation of the circuit is very important in the teaching of middle school, so it has always been an important content in junior high school physics teaching, and it is also the key content of the examination. Due to the complexity of such issues, it has always been a difficult teaching area. Circuit calculations involve more physical quantities, including current, voltage, resistance, electrical power, and electrical power, and their relationship is complex, but there are also rules that can be followed. As long as these laws are used flexibly, are there?
