FAQs

Question: What is the formula for capacitance?
Answer: The capacitance (C) is defined as C = Q/V, where Q is the charge stored and V is the potential difference across the capacitor.

Question: How does the electric field relate to electric potential?
Answer: The electric field (E) is the negative gradient of the electric potential (V), expressed as E = -dV/dx.

Question: What is the significance of equipotential surfaces?
Answer: Equipotential surfaces are regions where the electric potential is constant, meaning no work is done when moving a charge along these surfaces.
