电容器一直是高中物理的重要考点,高考几乎每年都有涉及,主要类型有:一、电容器的C、Q、U、E的变化随d、S、ε变化的规律1.电容器两端始终与电源相连这类问题由于电容器始终连接在电池上,因此两极间的电压保持不变,可根据下列几式讨论C、Q、E的变化情况。 Capacitors have always been an important test site for high school physics. The college entrance exams are involved almost every year. The main types are: 1. The variation of C, Q, U, E of capacitors varies with d, S, and ε. 1. The capacitors are always connected to the power supply For such problems connected, since the capacitor is always connected to the battery, the voltage between the two poles remains unchanged. The changes of C, Q, and E can be discussed according to the following formulas.
