We consider the capacitor shown in Fig. 23–4(a), which consists of two parallel circular plates connected to an external generator by a pair of wires. If we charge the capacitor with dc, there will be a positive charge on one plate and a negative charge on the other; and there will be a uniform electric field between the plates.
In order to obtain accurate measurements of capacitors, an LCR meter, such as the one shown in Figure 8.2.7, may be used.
