Electrical Engineering Experiment: KVL, KCL, Tellegen's Theorem

Study Notes

This experiment aims to verify Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL) for a DC network.
The circuit consists of a 25V DC source, 6 resistors with varying resistances, and 3 ammeters and 4 voltmeters to measure current and voltage drops respectively.
KVL verifies that the sum of voltage drops around a closed loop is equal to the applied voltage.
KCL demonstrates that the sum of currents entering a junction equals the sum of currents leaving that junction.
The experiment involves measuring current and voltage values at different locations in the circuit and comparing them to theoretical calculations based on KVL and KCL.

This experiment focuses on applying Tellegen's Theorem to determine specific voltage and current values in a DC network.
The experiment utilizes two separate networks:
- Network 1: Contains a 10V DC source, 3 resistors, one ammeter, and one voltmeter measuring the voltage drop across a resistor.
- Network 2: Contains a 20V DC source, the same 3 resistors as Network 1, one ammeter, and one voltmeter measuring the voltage drop across a specific resistor in Network 2.
Tellegen's Theorem states that for any linear network, the power supplied equals the power dissipated. It is used to calculate voltage and current values in Network 2 based on known values in Network 1.
The experiment involves comparing the theoretically calculated values of voltage and current in Network 2 against practical measurements taken from a physically constructed circuit.

This experiment focuses on determining the impedance (Z) and admittance (Y) parameters of a two-port network.
The experiment uses three different network configurations:
- π Network: A circuit with 3 resistors connected in a pi shape.
- T Network: A circuit with 3 resistors connected in a T shape.
- Parallel Connection of T and π Networks: A circuit with 5 resistors formed by combining the T and π configurations.
The values of Z and Y parameters are determined using both open-circuit and short-circuit tests.
The open-circuit test involves measuring voltage and current values with one port open, while the short-circuit test involves measuring voltage and current values with one port shorted.
The experiment involves comparing the measured values to theoretically calculated values for Z and Y parameters.
