FAQs

Question: What is Coulombs Law?
Answer: Coulombs Law states that the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Question: How does a dielectric affect capacitance?
Answer: A dielectric increases the capacitance of a capacitor by reducing the electric field within the capacitor, allowing it to store more charge for the same voltage.
