To demonstrate how does a capacitor work let us consider a most basic structure of a capacitorit is made of two parallel conducting plates separated by a dielectric that is parallel plate capacitorwhen we connect a battery dc voltage source across the capacitor one plate plate i gets attached to the positive end and another plate plate ii to the negative end of the battery. Once its charged the capacitor has the same voltage as the battery 15 volts on the battery means 15 volts on the capacitor. What Is The Exact Work Of The Two Capacitors In The Below How Do Capacitors Work Explain That Stuff Tantalum Capacitor Uses Differences Oftantalum And Ceramic Its pretty fair to say that its nearly impossible to find a functioning circuit without using capacitor. Capacitor working in circuit . The plate on the capacitor that attaches to the positive terminal of the b
