These aluminum electrolytic capacitors are common residents on circuit boards. We may have cut one open to satisfy our curiosity of what’s inside, but that doesn’t necessarily mean we ...

Inside the box? Two capacitors as predicted. The repair was quick and then it was just a matter of putting it back together with a new cardboard box, some rivets, and new grommets.

Capacitors retain an electrical charge over a period of time. The charge bleeds off through the internal resistance of the capacitor or decays through resistors, such as those in the bias network. No ...

The electric charge on these plates creates an electric field inside the capacitor. Since there is an electric field, there must also be a change in electric potential across the plates.

The inside of the capacitor is filled with an oil that helps to dissipate heat from the capacitor, and metal run capacitors have a plastic insulating liner that separates the metal from the oil. A ...

We built a fully functional Mjölnir with a 300V capacitor inside—and the results were shocking. Sparks fly, circuits hum, and the hammer actually packs a punch. Warning: not for mere mortals.

The early 2000s capacitor plague is probably not just a stolen recipe Video takes a wider look at the busted caps of early 2000s PCs and other gear. Kevin Purdy – Mar 20, 2025 2:04 pm | 112 ...

In the introductory physics course, capacitors are typically introduced for one main reason: the electric field inside a capacitor is essentially constant. Constant is nice.
