7. What is the value of capacitance of a capacitor which has a voltage of 4V and has 16C of charge? Explanation: Q is directly proportional to V. The constant of proportionality in this case is C, that is, the capacitance. Hence Q=CV. From the relation, C=Q/V= 16/4=4F.
Where C = capacitance, A = area of the two plates, ε o = permittivity of free space and d = separation between the plates, From the above equation, it is clear that the capacitance of the capacitor is directly proportional to the area of the parallel plate capacitor.
The voltage rating of a capacitor indicates the maximum voltage that can be safely applied to its plates and depends on the insulation strength of its dielectric. 7. To provide a total capacitance of 100µF, how would you connect two 50µF capacitors? In parallel. 8.
