Chapter 5 Capacitance and Dielectrics
0 parallelplate Q A C |V| d ε == ∆ (5.2.4) Note that C depends only on the geometric factors A and d.The capacitance C increases linearly with the area A since for a given potential difference ∆V, a bigger plate can hold more charge. On the other hand, C is inversely proportional to d, the distance of separation because the smaller the value of d, the smaller the potential difference …
18.5 Capacitors and Dielectrics
The equation C = Q / V C = Q / V makes sense: A parallel-plate capacitor (like the one shown in Figure 18.28) the size of a football field could hold a lot of charge without requiring too much work per unit charge to push the charge into the capacitor. Thus, Q would be large, and V would be small, so the capacitance C would be very large.
Introduction to Capacitors, Capacitance and Charge
Capacitance is defined as being that a capacitor has the capacitance of One Farad when a charge of One Coulomb is stored on the plates by a voltage of One volt. Note that capacitance, C is always positive in value and has no negative …

Of course this does not satisfy the initial condition which is that the capacitance be uncharged: ( v_{c}(t=0+)=0). Again, remember that the whole solution is the sum of the particular and a homogeneous solution, and that the homogeneous solution is the un-driven case. To satisfy the initial condition, the homogeneous solution must be:

Isaac Physics
The voltage between the plates and the charge held by the plates are related by a term known as the capacitance of the capacitor. Capacitance is defined as: C = V Q The larger the potential across the capacitor, the larger the magnitude of the charge held by the plates. The capacitance is dependent only on the capacitor''s geometry and the type ...
