SUMMARY
The electric field (E) across a parallel plate capacitor is determined by the configuration of the circuit. In a series circuit with a resistor (R), the electric field is given by E = (V - IR)/L, where V is the potential source and L is the distance between the plates. Once the capacitor is fully charged, the electric field simplifies to E = V/L. Conversely, in a parallel configuration, the electric field remains constant at E = V/L, as all components share the same potential.
