This document is a laboratory report for the Circuit Theory course within the Department of Informatics and Computer Engineering at the University of West Attica.
The project focuses on the study and analysis of the resonance effect in RLC circuits. It explores the behavior of resistors, inductors, and capacitors when connected in series and parallel configurations across varying frequencies.

The report is structured into:
- Theoretical Analysis
- Software Simulations using Multisim
- Experimental Laboratory Results
Theory:
Analysis of the frequency at which the inductive reactance (Xₗ) and capacitive reactance (Xc) cancel each other out.
Key Observations:
- The impedance (Z) becomes equal to the ohmic resistance (R) at resonance.
- Maximum current flow occurs at the resonant frequency.
- Overvoltage phenomena are observed across the capacitor and inductor.
Formula Used:
Where:
- (f_r) = resonant frequency
- (L) = inductance
- (C) = capacitance
- Theoretical solutions and simulation results for parallel RLC configurations.
- Detailed analysis provided in the report (pages 12–17).
The experimental work utilized the following tools:
- Multimeters (Analog and Digital)
- Oscilloscope
- Breadboard
- Passive Components:
- Resistors
- Capacitors
- Inductors
