Best Answer

The smallest unit of electric charge is the charge on an electron. It's not possible

to split that amount of charge in pieces.

-- 6,241,509,752,000,000,000 of them make 1 coulomb of charge.

-- When that many of them flow through your ammeter every second,

the meter reads 1 Ampere of current.

-- It takes 1 joule of energy to lift that many of them through 1 volt of potential difference.

When you let the same number fall down through the volt, they give back the joule.

-- The proton has the same amount of charge, but it has opposite polarity.

Whatever that really means.
