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

Answer 1

Internal resistance in the capacitors and wires limits the amount of current that can flow, thus increasing the amount of time it takes to charge.
