OBJECTIVE
The objectives of this experiment are to investigate and verify the Thevenin’s theorem and to investigate and verify the Norton’s theorem. EQUIPMENT
Resistor 100Ω, 1kΩ and 4.7kΩ, digital multimeter(DVM), bread board. INTRODUCTION
Some circuits require more than one voltage source. Superposition theorem is a way to determine currents and voltages in a linear circuit that has multiple sources by taking one source at a time. the current in any given branch of a multiple-source linear circuit can be found by determining the currents in that particular branch produced by each source acting alone, with all other sources replaced by their internal resistances. The total current in the branch is the algebraic sum of the individual source currents in that branch. Thevenin’s theorem provides a method for simplifying a circuit to a standard equivalent form. This theorem can be used to simplify the analysis of series-parallel circuits. The Thevenin’s equivalent voltage (VTH) is the open circuit (no-load) voltage between two specified output terminals in a circuit. The Thevenin’s equivalent resistance (RTH) is the total resistance appearing between two specified output terminals in a circuit with all sources replaced by their internal resistance. Another method for simplifying a circuit to an equivalent form is Norton’s theorem. By reducing all of the element of a complex circuit to a single current source and a single source resistance, which supply power load, a simple circuit can be created.

PROCEDURE
Experiment 1: Super position theorem

Figure 1
The circuit connected as shown in figure 1. The current flow through each resistor is measured by using DVM. the current flow in each resistor are measured when V1 is removed. V 1 is reconnected and V2 is removed and the current flow in each resistor is measured. The values are recorded in Table 1. The actual current flows through each resistor are determined by superimposing all the currents in PART A...

Lab Report#1 Measurements in resistive networks and circuit laws laboratory
Abstract:
The purpose of this lab is to verify the Ohm's Law, Kirchhoff's Voltage and Current Laws. As well as the introduction to the voltage division. The Ohm's Law states that the current through a conductor between two points is directly proportional to the potential difference across the two points (V = IR). The Kirchhoff's Voltage Law states...

Abstract:
The aim of this experiment was to understand the relationship between the variables of Ohm’s law and how they are part of an operation of an electric circuit.
Introduction:
This experiment was done in two parts. The first part consisted of understanding...

...Ohm’s Law is V = I * R or in some cases I = V / R. The next two laws were established by a German physicist by the name of Gustav Kirchhoff. Kirchhoff’s first law is his voltage law. Kirchhoff’s Voltage Law (KVL) states that around any loop in a circuit, the voltage rises must equal the voltage drops. The next law that Kirchhoff introduced was his current law. Kirchhoff’s Current Law (KCL) states that the total current entering a junction must equal the total current leaving the...

Experiment 5: RC Circuits
Abstract
The purpose of this lab is to learn and understand RC Circuits. An RC circuit is composed of at least one resistor and at least one capacitor. A capacitor is composed of two plates with either air or an insulator also known as a dielectric between the plates. We do not want the plates to be touching, because then we would only have a conductor. The insulator between the...
