If electricity is so fast, how it doesn’t immediately charge up capacitors and batteries?

Question

I’m pretty aware that this is a “dumb” question, but my basic understanding of electricity can’t figure it out. I know the basic concept of resistance, currency and voltage, but I can’t comprehend how it takes so long to store charge in a battery

Because it’s not about how fast the electricity moves, but how much of it moves at a time. The limiting factor here is wire size. It’s like comparing a garden hose and a fire hose. By increasing the size you allow more water to flow at the same pressure.
