How do we measure electrical current
WebDec 15, 2024 · 1 ampere is equivalent to 6.24 x 10^18 electrons flowing per second. You don’t need to memorize that number but you should understand that electrical current refers to the amount of electron flow. And one ampere means that a lot of electrons are flowing. Two amps means that twice that amount of electrons are flowing. WebApr 26, 2024 · To measure current in an electrical circuit we need to use a piece of electrical testing equipment. Clamp meters and ammeter can be used but in this example below we will be using a multimeter. The multimeter must be connected to the circuit so that the electrons can flow through it.
