current - the number of charges that pass any given point in a circuit per unit time,
often measured in Amperes

voltage - the work done (or the energy delivered) per unit charge, usually measured in volts.

Also known as potential difference
Also known as EMF (Electromotive Force)

Electric Field Intensity - The force per unit charge experienced by a charged particle situated in an electric field. Measured in N/C = V/m

resistance - the opposition to the flow of current, usually measured in ohms

power -- the work delivered (or the energy consumed) per unit time, usually measured in Watts

resistivity - a property of matter that determines how well electrons flow through the matter

Ampere - the unit - a Coulomb per second

Volt - the unit - Joule per Coulomb

Watt - the unit - a Joule per second

Ohm - the unit - a Volt per Ampere

Series connection - the union of components in such a way that every charge that passes through one component passes through the other component

parallel connection - the union of two components wherein the circuit branches out into two (or more) pathways before coming together again to a single point
