Electrical Engineering Concepts - RLC Circuits

These flashcards cover key concepts and definitions related to RLC circuits and electrical engineering topics, helping students prepare for exams.

Inductor

A coil that stores energy in a magnetic field.

Capacitor

A device that consists of two plates with an insulator in between, used to store electrical energy.

Inductive Reactance

The opposition of an inductor in an AC circuit.

Capacitive Reactance

The opposition of a capacitor in an AC circuit.

Impedance

The total opposition offered by the RLC components in an AC circuit.

Phase Angle

The shifting in phase between the supply voltage and the current in the circuit.

Power Factor

The ratio of true power to apparent power.

Resonance

The increase in amplitude of a system under external periodic impulse.

Quality Factor (Q)

A measure of how good a circuit is at resonating at a particular frequency.

Bandwidth

The upper and lower half power frequency directly affected by the quality factor.

Three Phase System

A system that produces alternating voltage with the same magnitude and frequency.

Single Phase System

A system used primarily in residential applications, with lower voltage and cheaper appliances.

Active Power

The power capable of performing work in a circuit, measured in Watts.

Reactive Power

The power expended in a purely inductive or capacitive circuit.

Apparent Power

The product of the voltage and current in a circuit.

Efficiency

The ratio of output power to input power, expressed in percentage.
