As the elements of the triode are made of metal and are separated by a dielectric, capacitance exists between them. This capacitance is called interelectrode capacitance, and is schematically represented in figure 1-29. Figure 1-29. - Schematic representation of interelectrode capacitance.
Finally, the individual voltages are computed from Equation 6.1.2.2 6.1.2.2, V = Q/C V = Q / C, where Q Q is the total charge and C C is the capacitance of interest. This is illustrated in the following example. Figure 8.2.11 : A simple capacitors-only series circuit. Find the voltages across the capacitors in Figure 8.2.12 .
When a voltage V is applied to the capacitor, it stores a charge Q, as shown. We can see how its capacitance may depend on A and d by considering characteristics of the Coulomb force. We know that force between the charges increases with charge values and decreases with the distance between them.
