Vooluahelaelement on sisuliselt elektriseadme/-mõõtevahendi matemaatiline mudel, mida iseloomustab täielikult selle pinge ja voolu vaheline seos. Põhilise ehitusplokina ei saa vooluahelaelementi jagada lihtsamateks komponentideks.
An circuit element is essentially the mathematical model of an electrical device, fully characterized by its voltage and current relationship. As the most basic building block, a circuit element cannot be subdivided into simpler components.
