For example: The voltage across all the capacitors is 10V and the capacitance value are 2F, 3F and 6F respectively. Draw and label each capacitor with its charge and voltage. Once the voltage and charge in each capacitor is calculated, the circuit is solved. Label these information in the circuit drawing to keep everything organized.
When capacitors connected in series, we can replace them by one capacitor with capacitance equal to reciprocal value of sum of reciprocal values of several capacitors’ capacitances. So we can evaluate the total capacitance. Total charge is directly proportional to the total capacitance and also to the total voltage (i.e. power supply voltage).
For finding the capacitance of the capacitor having continuously varying dielectric, we would have to perform integration over whole variation. The Potential Difference between AB is 6 V. Considering the branch AB, the capacitors 2 μ F and 5 μ F are in parallel and their equivalent capacitance = 2 + 5 = 7 μ F.

(1) Identify the direction of the electric field using symmetry. (2) Calculate electric field everywhere. (3) Compute the electric potential difference ∆V. = ∆ .
First we would have to calculate the charge and voltage on each capacitor. Given that capacitance of both the capacitors is same let it be C. Since both the capacitors are connected in series combination so charge on both the capacitors would be same which lead to same potential difference V across each capacitor which is
Given the voltage and capacitor values for each, find the total capacitance. To calculate the total capacitance in a series circuit, use the formula For example: A series circuit has three different capacitors of value C 1 = 2F, C 2 = 3F, C 3 = 6F. Plug in to the formula and solve for C T. Adding the fraction and taking the inverse, C T = 1F.
