Final answer:
To find the equivalent capacitance in a circuit, consider if capacitors are in series or parallel. In parallel, equivalent capacitance is the sum of individual capacitances, and for capacitors in parallel with a voltage source, the voltage across each is equal to the source voltage; charge can be determined with Q = CV.
Step-by-step explanation:
To find equivalent capacitance for a given circuit and determine the voltage across each capacitor, we must consider whether the capacitors are in series or parallel. In parallel, the equivalent capacitance is simply the sum of the individual capacitances. Using the formulas C = Q/V and V = Q/C, we can determine both the charge on each capacitor and the voltage across it given a potential difference applied to the network. For example, if three capacitors with capacitances of C1 = 2.0 µF, C2 = 3.0 µF, and C3 = 6.0 µF are connected in parallel with a 500-V potential difference applied across them, the voltage across each capacitor is 500 V, as they are connected directly to the voltage source. The charge on each capacitor can be calculated using Q = C×V.
