Week 4

Title of Activity
-Do the abstract and introduction about the project.

Objective
- To do a brief explanation about the project.
-To do the introduction about the project.

Content/Procedure
-Abstract about the voltmeter including a brief explanation about the project.
-Introduction about the voltmeter, analog and digital voltmeter what is the voltmeter and who create the voltmeter.

Result/Analysis
 -As a result, the voltmeter is used in parallel with the load. So the voltage between the two terminals of the load is equal to the voltage between the two terminals of the voltmeter.
-Voltmeter accuracy is affected by many factors, including temperature and supply voltage variations. Digital voltmeters necessarily have input amplifiers and like vacuum tube voltmeters, it generally has a constant input resistance of 10 mega ohms regardless of set measurement range.
-The development of talking voltmeter is to get the fun working place in the lab. The features of this tool include a talking voltmeter, logic probe, voltage average, and frequency measurer. As a cheap and accurate device that outputs being measured through speakers, it's one of its kind and an essential tool for lab work.

-A new idea by developing a talking voltmeter is proposed. The idea of this project is to produce a digital and talking voltmeter to make sure it is more accurate and less calibration.
-By producing this project it will make measuring the voltage become easier since the instrument is a user-friendly to be used as a lab tool.


Conclusions
 As a conclusions, this project will be benefited not only for those technicians who are working in lab, but also for the students and engineers who are involved in engineering sector where measurement is appropriate. A device has a "talking" ability at a very cheap cost is not available in the market today and is very useful to the ordinary engineer.
