Let us say that the potential drop across the capacitor is 2V. The potential of the charge after crossing the capacitor (displacing another charge on the low potential plate) will be 3V. What confuses me is the assumption that the high plate will be at 5V as well since only then the potential of the low potential plate can be said to be 3V.
The electric potential energy is 1 q 2. Note that the potential energy of two charged particles approaches zero as r → ∞. charges. Each + symbol represents the same amount of charge. where s is the distance from the negative electrode. The electric potential, like the electric field, exists at all points inside the capacitor.
The energy stored in a capacitor is nothing but the electric potential energy and is related to the voltage and charge on the capacitor. If the capacitance of a conductor is C, then it is initially uncharged and it acquires a potential difference V when connected to a battery. If q is the charge on the plate at that time, then
The work done is equal to the product of the potential and charge. Hence, W = Vq If the battery delivers a small amount of charge dQ at a constant potential V, then the work done is Now, the total work done in delivering a charge of an amount q to the capacitor is given by Therefore the energy stored in a capacitor is given by Substituting
As discussed above, the spreading causes the droplet to touch the electrode and discharge the capacitor. Furthermore, this spreading increases the droplet’s potential energy because of the hydrophobic interaction between the droplet and the surface—much like pulling on a spring increases its potential energy.
The expression in Equation 8.4.2 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 between its plates.
