Measurement for voltage and current for the resistor were obtained and recorded and a graph of V against I plotted to determine the value of R from the slope. In order to prove the validity of ohm’s equation, the experiment involved comparison of the experimentally and directly measured values for the resistor R. The following equation was used:
The experiment have illustrated succinctly that the relationship between the flow of current and the flow of charge in a material results to the resistance. In which case, the flow of electric current is responsible for the generation of heat owing to the collision of free electrons. This insinuates and supports the ohm’s law, which relates between the current and voltage. For the resistors, a graph plotted for V against I gave a straight line from the origin thereby supporting the law, which states “the amount of voltage flowing from one point to another end in a conductor is directly proportional to the current between the two points, while keeping the temperature constant”. Further, the difference between the value of R from slope of graph and that from direct ohmmeter reading was insignificant thereby proving the success of the experiment.
The electric resistance in material arises from the generation of heat as the result of collision of free electrons, when electric current flow (I). In which case, the heat generated opposes the flow of electrons (charges) ( V) through the material hence the resistance.
For the resistors, a graph plotted for V against I gave a straight line from the origin thereby supporting the law which states that “the amount of voltage flowing from one point to another end in a conductor is directly proportional to the current between the two pointsl, while keeping the temperature constant

...?Pressure Sensitive Paint technique for pressure measurement Pressure sensitive paint is a technique used for measuring the level of air pressure or the concentration of oxygen in aerodynamic environments (Sullivan & Liu 2004). Research has indicated that the pressure sensitive paint technique is the most effective method for measuring pressure in aerodynamic environments. This technique provides global surface pressure maps with great resolutions for both complex and simple surfaces. However, there are various challenges that hinder the accuracy of the results obtained from the pressure surface paint technique. One of the challenges of this technique is that the preparation of and...

Circuits design and application
...the output of the analyzer is audio, so it can use any scope for the display. The analyzer functions as a Tunable RF Voltmeter. This makes it function as a natural receiver / transmitter tracing signals. A display of the frequency is provided using the analyzer on a transmitter. Owing to the high sensitivity of the instrument signal tracing receiver circuits are permitted from the antenna through the low-level Radio Frequency stages. Whereas a conventional RF voltmeter adds up all the individual voltages as a summation without indicating the components it is not the case with a spectrum analyzer. Additionally the analyzer displays local oscillator signal and its frequency and injection levels. A tracking generator...

... that paint different scenarios that could be problematic. Then from the options developed, narrow them according to the characteristics displayed. By elimination, an accurate diagnosis of the problem is made possible. A good understanding of the basic electrical principles is necessary for the effective diagnosis of electrical problems. I discovered, in my hunt, that troubleshooting is often carried out with the help of a voltmeter, ammeter, and ohmmeter (Electrical Circuit Theory). Without these instruments, electrical troubleshooting is not possible. A technician uses a schematic diagram to determine what switches and controls are in series with every component. The voltmeter is useful in measuring the voltage in the system... depending...

...to identify the defected system, whether it is electrical or mechanical. This should be followed by a thorough analysis of the fault found in the identified system. Carrying out the troubleshooting steps would then follow for repairs. These techniques would make the troubleshooting a lot faster. In the scope of troubleshooting an electrical circuit, it is likewise of utmost importance to identify the controls and loads, clearly understand the sequence of the operation in a system, and the mastery of the basic circuit theory which will help in the analysis of the individual components at hand. To make the troubleshooting more systematic, I should look at...

Economic measurements
...Gross Domestic Product Gross domestic product helps measure the economic activity of a country in terms of the value of thegoods and services it produces in a certain period. It can be expressed as nominal gross domestic product or real gross domestic product. Nominal gross domestic product uses incumbent prices to express the value of goods and services produced in a country at a given period. Real gross domestic product expresses a country’s value of goods and services using constant consumer and producer price indices in removing the effects of inflation. Real gross domestic product shows that the economy of a country is growing and that average incomes are increasing consumption. Negative real gross domestic product...

...Laboratory Number: Op-Amp Circuits Lab Performance Submitted Dominick Lauria Lab Partner: Introduction: The instrumentation Amplifier is an improvement of differential amplifier circuit; its CMRR is not dependent on internal resistance of the sources. This is due to the summing point constraints at the lower and upper LM1458C inputs; there is no current is drawn from the signal source. These implies that the input impedance is seen by both sources as infinite therefore the output voltage is unaltered by the internal sources impedance, for example V1a=V2b=19.9V.
