This means that the recharge time for the flash is limited by the power output of the battery, rather than the power output of the flash. The battery has a lower power density than the capacitor in the flash. Power density is also why it takes time to recharge your flash in between photos. This makes a system with a high power density ideal. It has to be small enough to fit inside the camera (or cell phone) but have a high enough power output to light up the subject of your photo. Since they release their energy quickly, high power density systems can also recharge quickly.Īn example application of this type of energy storage is a camera flash. Because the capacitor is so much smaller, it has a higher power density. For example, a tiny capacitor may have the same power output as a large battery. If a system has a high power density, than it can output large amounts of energy based on its volume. It's helpful to understand power density vs. While it is not as commonly used a measurement as energy density, it is still useful for conversations about energy systems (often for portable applications like transportation). Power density is a measure of power output per unit volume. The jug has more water (more 'energy') than the mug though. Comparatively, if you upended the jug, it would take awhile to release its contents, giving it a low power density. The mug has a high power density, because it is capable of emptying all its contents almost instantaneously.
