Essays on Resistivity

Abstract:

The principal intention of this study was to come up with the most conducive internal environment in a building. At any given moment, the internal temperature of a building is a function of the amount of heat produced by sources therein and the net heat transfer into or out of the building. The four heat transfer modes are convection, radiation, conduction, and phase- change. In executing this project, the researchers sought the relevant literature to establish the thermal properties of various materials. The properties are critical in determining the amount of heat inflow and exit from the building. The ...

Introduction

Taking measurements may require the conversion of the measured quantity to electrical quantity. Transducers are devices or elements that perform this function by transforming physical quantities such as quantities like sound, light, or temperature into electrical signals like current, voltage, or capacity. Transducers consist of inputs, sensing elements, transduction elements, signal processing, and electrical outputs. The inputs known as the measurands are the quantities, states, or properties that are to be translated into electrical outputs. The sensing elements accurately measure these input energies and sends the information to the transduction elements to be transformed into the desired form. The ...

Lab Report

Introduction This lab experiment involves choosing values of the resistors, that will enable maximum output of power in circuit two, according to the circuit connection made. The aim is determining values of the resistors that will enable increase in power up to 2.7 kilo ohms. Results were then tabulated.

Apparatus

Resistors Oscilloscope Digital multimeter Function generator Breadboard Procedure The apparatus were arranged to form a complete circuit, whereby resistor values were first were determined sequentially. The resistor value that would enable a resistivity value of 2.7 kΩ was the determined. The set up was done according to the figure below ...
