FAQs

Question: What is the difference between electric potential and electric potential energy?
Answer: Electric potential refers to the potential energy per unit charge at a point in an electric field, while electric potential energy is the total energy a charge has due to its position in the field.

Question: How do capacitors behave in series and parallel circuits?
Answer: In series, the total capacitance decreases, while in parallel, the total capacitance increases. Understanding these configurations is essential for circuit analysis.
