A circuit is an interconnection of electrical elements, including passive elements and active elements. Active circuit elements can deliver a non-zero average power indefinitely. 

Some circuit variables and elements are:
Voltage: A basic parameter that describes the electrical conditions in a circuit.
Current: A variable associated with each circuit element.
Power: Represents the power absorbed by the element through which current flows.
Linearity: A property of an element that describes a linear relationship between cause and effect.
Inductor: A passive circuit element that stores energy as a magnetic field and supplies it to the circuit.
Current source: A circuit element that provides a specified amount of current.
