Ex. 1
Four capacitors are connected as shown in Figure
P26.21. (a) Find the equivalent capacitance between
points a and b. (b) Calculate the charge on each
capacitor if ΔVab = 15.0 V.
Ex. 2
Find the equivalent capacitance between points a and b for
the group of capacitors connected as shown in the figure.
Take: C1 = 5.00 μF, C2 = 10.0 μF, and C3 = 2.00 μF.
