Common misconceptions are highlighted and corrected with solutions, such as:

• A conductor's internal electric field is always zero (not only for spherical shells).
• Inside a conductor, including in charge-free cavities, the potential remains constant.
• Because of the redistribution of charge, energy is always lost when a charged capacitor is linked to an uncharged one.
• Capacitance is not directly influenced by charge or potential, but rather solely by geometry and dielectric.

For higher-order exam problems, this guarantees conceptual clarity.
