The expression in Equation 8.10 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q / C V = q / C between its plates.
Once you have Ceq, you can determine the potential difference across each capacitor using the formula: V1 = (Ceq / C1) * Vs, V2 = (Ceq / C2) * Vs, V3 = (Ceq / C3) * Vs, where Vs is the total applied voltage . In the case of capacitors in parallel, the potential difference across each capacitor is the same and equal to the applied voltage.
When capacitors are connected in series, the potential difference across each capacitor depends on the ratio of its capacitance to the total equivalent capacitance of the series combination.
In a circuit with capacitors, the potential difference can vary depending on the circuit configuration. Let’s consider two common configurations: capacitors in series and capacitors in parallel. When capacitors are connected in series, they share the same current but have different voltage drops across them.
Each capacitor in the series has a different potential difference, and the total potential difference is divided among them according to their capacitance values. On the other hand, when capacitors are connected in parallel, the potential difference across each capacitor is the same and equal to the applied voltage.
The potential energy stored in a capacitor can be calculated using the formula: U = (1/2) * C * V^2, where U represents the potential energy, C is the capacitance of the capacitor, and V is the potential difference or voltage across it. Useful Video: find the charges on the capacitors in figure. And the potential differences across them.
