Pressure and speed are totally different and unrelated things!

NO! Perhaps a different analogy will clarify things. Try thinking of
electricity as a gas and the amount of gas is the current and the
pressure of the gas is the voltage. Using this analogy a capacitor
would be a storage tank. if you had 1000 cubic feet of gas in a
container and connected it to a 1 cubic foot cylinder and the gas was
under 1 atmosphere of pressure then the cylinder would hold 1 cubic
feet of gas. You could have 100,000 cubic feet of gas connected to
that same cylinder and it still will only hold 1 cubic feet of gas.
BUT if you increase the pressure to say 10 atmospheres THEN you would
be forcing more gas into the cylinder.

Sincerely
