Final answer:
The equivalent capacitance between A and B for the group of capacitors if C1 = 9 µF and C2 = 3.0 µF is 12 µF.
Step-by-step explanation:
To find the equivalent capacitance between two points for given capacitors, it is essential to know whether they are in series or parallel, and then apply the corresponding formula for series or parallel capacitance.
The equivalent capacitance between A and B for the group of capacitors in the drawing can be determined by analyzing the configuration. In this case, C1 and C2 are in parallel, and their total capacitance can be calculated using the formula for capacitors in parallel:
C_parallel = C1 + C2 = 9 µF + 3.0 µF = 12 µF
Therefore, the equivalent capacitance between A and B is 12 µF.
