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 that the directed sum of the electrical voltage around any closed network is zero. The Kirchhoff's Current Law states that the algebraic sum of currents in a network of conductors meeting at a point is zero. This lab report presents the lab results of 4 different parts of the lab and they provide experimented data, both numerical and visual, that verifies the Ohm's Law, Kirchhoff's Voltage and Current Laws.

Graph 1.1 -The plot on the does not go through the origin, but it should. Ideally, when the voltage source is equal to 0V, both the voltage and the current should be 0V and 0mA respectively which will make the plot go through the origin; however, because of the resistance from the voltmeter, the actual readings of voltage and the current when measured are a bit off from 0V(0.19V) and 0mA(0.09mA). -Unknown resistance (actual given value is equal to 2.2 kΩ) is the slope of the linear line of the graph, R ≈ 2.169kΩ

...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...

DC Circuits - Analysis and Design
Alexander Glover, z3422512
Abstract
DC circuit analysis and design, play a massive role in electrical engineering and without the correct application of theory and practise in unison, nothing can be achieved in a true engineering sense. Engineering requires theory to develop and test constraints while also requiring practical application of theory in order...

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...

RE: Electrical Circuit Project LabReport
The purpose of the Electrical Circuit project was to prepare students with the ability to work with mathematical and engineering calculations to design a breadboard. In order to create a breadboard with an accurate voltage drop between nodes, the resistor combinations and calculations need to be correct....

...Ohm’s Law II
Abstract:
The purpose of this experiment is to demonstrate how non-ohmic devices respond on a direct circuit. Furthermore, we also explored their behavior when they were connected in different configurations. In order to accomplished this we used a capacitor, diode, resistor, and battery. We ran a series of experiments that generated graphs and equations, which can explain the relationship between voltage and time for capacitors and diodes. Non-ohmic...
