Question

If a capacitor is essentialy two plates separted by an insulator how come it doesnt act as an open circuit from the start. And if electrons flow from negative to positive, how do they flow passed the capacitor and into the positive pole? Ive had this question for long time now and I solve all my circuit problems without understand this concept! If anyone can give me a detailed explanation that would be great! If you also decide to add some math calculations and physics that would be even better!!

Explanation / Answer

In a capacitor only electric field gets across from one plate to the other. Without the electric field a capacitor would be just another open circuit. When you apply a voltage over the two plates, an electric field is created. Positive charge will collect on one plate and negative charge on the other. And this mean a capacitor works by storing energy electrostatically in an electric field.
