FAQs

Question: What is Ohm's Law?
Answer: Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, expressed as V = IR.

Question: How do dielectrics affect capacitance?
Answer: Dielectrics increase the capacitance of a capacitor by reducing the electric field strength, allowing it to store more charge at the same voltage.
