ECE Board Examination: Electrical Units and Fundamental Concepts

Practice vocabulary flashcards covering fundamental electrical units, matter, and conductor resistance based on the ECE Board Examination questions.

Ampere

The standard unit of electric current.

Joule

The standard unit of energy.

Matter

Anything that has weight and occupies space, which may exist as a solid, liquid, or gas.

Resistance Proportionality to Length

The direct relationship where doubling the length of a conductor doubles its resistance; for example, a $0.5\,\Omega$ wire conductor doubled in length becomes $1.0\,\Omega$.

Electrical Quantity

A measurable physical property associated with electricity, such as current, voltage, or power.
