Ohms Law and DC Series Circuits
Objective: The objective of this lab was to calculate the dc voltage and current across resistors in DC series circuits. Also to calculate the power supplied using the voltage and cur
1. Introduction
The purpose of this report is to give methods for gaining experience in
testing voltage, current, and power across and through DC series, parallel, and
series-parallel combination circuits. This is accomplished three ways: by
implementing
1. Introduction
The purpose of this experiment was to demonstrate voltage division, circuit
reduction, and node voltage analysis. This was accomplished by constructing and
analyzing a voltage ladder circuit, a series / parallel circuits, and a Wheatstone
1. OBJECTIVES
The objective of this experiment was to find the Thevenin equivalencies for
three separate circuits. The circuits and their VTH, ISC, and RTH were analyzed
using PSPICE, hand calculations, and DMM use on breadboard reproductions.

1. Introduction
The objective of this lab was to gain experience with AC signals and circuit
measurements. This was accomplished by generating AC signals with a function generators and
then measuring this signals with both digital and analog oscilloscopes
