Ammeters: Circuit Instruments

While the DMM can handle this amount of current, you must learn how to use the ammeter portion of the DMM properly to protect it from blowing a fuse. Shorting voltage sources is dangerous and can damage the DMM.

kindly find below the information for this meters and we will take the reading next week to check and compare between analog and digital meters to get final result

The United States has to reconfigure the measurement of goods due to not using the metric system.

Due to the microquantities being used, all chemicals will be disposed up with running water. Gloves, an apron, and splash goggles will be used to protect the eyes and skin.

Purpose: To learn about the international system of units (SI), to become familiar with common lab equipment and techniques, to gain proficiency in determining volume, mass, length, and temperature of a variety of items using common laboratory measurement devices, to learn to combine units to determine density and concentration, and to use laboratory equipment to create serial dilutions and determine the density and concentration of each dilution.

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

Purpose: To become familiar with the International System of Units and common laboratory equipment and techniques. To learn how to determine volume, mass, length, and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions.

4. What are the benefits of using a light bulb as an indication of conductivity? What are the disadvantages? The benefits are: it acts as a confident and direct way of determining whether a solution should be classified as strong, weak, or non-electrolyte. A strong light would indicate a strong electrolyte. A dim light indicates a weak electrolyte, and no light indicates a non-electrolyte. However, the disadvantages are the lack of accuracy in each reading, and conclusions that aren’t necessarily precise. Each reading displays a different level of light for each bulb. Therefore, conductivity

The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10, and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data table 1. The second experiment was to measure temperature of how cold and hot tap water can be by using thermometer in Celsius units. From this experiment, gained knowledge that tab water doesn’t boil to 100 Celsius related to containing different

The purpose of this lab was for the student to get involved with his or hers new lab kit as well as being able to know, identify and use each other tools provided in the kit. Another key learning aspect of this lab is to teach the student how to measure properly the many units in the SI system. I will be using laboratory dilutions, measurements, and weights to then calculate using algebraic formula.

In the book, “The Circuit” by Francisco Jimenez, some examples are given on how family and culture can influence one’s life. Family and culture can negatively affect a person’s life because in the narrator’s case, it can cause them to move away from their friends or work hard to support their family. For example, “As the last days of August disappeared, so did the number of braceros. Sunday, only one—the best picker—came to work. I liked him. [...] That Sunday was the last time I saw him. [...] The thought of having to move to Fresno and knowing what was in store for me there brought tears to my eyes” (Jimenez 2 and 5). In other words, the narrator had to leave because the harvesting season was over and they had to find another place to work.

The oscilloscope, or scope for short, is a device for drawing calibrated graphs of voltage vs. time very quickly and conveniently. Such an instrument is obviously useful for the design and repair of circuits in which voltages and currents are changing with time. There are also many devices, called transducers, which convert some non-electrical quantity such as pressure, sound, light intensity, or position to a voltage. By using a transducer the scope can make a plot of the changes in almost any measurable quantity. This capability is widely used in science and technology.

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason?

commonly used to amplify current. A small current at its base controls a larger current at

Electrical engineers use a lot of products and tools to help them have an easier job. The 2nd article talks about some products, electrical engineers use and explains what they do. One product they use is a “Power analyzer”. The power analyzer is “used to test product efficiency and the design of inverters, lighting systems, uninterruptible power supplies, aircraft power systems, and renewable energy generation products” (Ee Product Picks ). The analyzer test a lot of stuff which helps them waste less time and know if it is too much energy or just the right amount. “The power analyzer was designed for both today's power measurements and the advanced complex requirements of future power conversion products.” ( Ee Product Picks ). Electrical engineers have to use the power analyzer to see if things are safe enough. The product is fast and they will know what the problem is with what they are testing. Electrical engineers have an impact on the world by making sure that energy levels are fine and safe to have in this world by using this helpful tool, but with help, there are also concerns in electrical engineering.
