What Does a Capacitor Do | Explanation | Albert Resources

You can think of a capacitor as an energy storage tank. Just like a water tank holds water, a capacitor holds energy. When we need the energy, similar to opening a tap, the capacitor provides it back to the circuit. Similarly, in parallel, capacitors are connected side by side. They all experience the same "pressure" (or voltage), but
