(a)找到如图所示连接的电容器组A和B之间的等效电容。以C1 = 5µF,C2 = 10µF、C3 = 2µF(B)是电荷存储在C3如果A点和B点之间的电位差为60 V?(a) Find the equivalent capacitance between points a and b for the group of capacitors connected as shown in the right Figure. Take C1 = 5.00µF, C2 = 10.0µF, and C3 = 2.00µF. (b) What charge is stored on C3 if the potential difference between points a and b is 60.0 V?
