you use these instruments properly and measurements alternating current correctly. One of the most common and economical methods for measuring alternating currents is to rectify these currents and read the resultant DC on an analog or digital volt-ohm meter (VOM). You need to take many considerations into account when using rectification: what type of rectification you use‚ what scale conversion you will need‚ and the sensitivity of the meter. RECTIFICATION Alternating current periodically changes

Eddy Current 1. The principles of eddy current testing depend on the process of electromagnetic induction. 2. This process includes a test coil through which vary or alternating current (AC) is passed. 3. A varying current flowing in a test coil produces a varying electromagnetic field around the coil‚ As shown in this diagram Amperage * # of coils= strength of magnetic field 4. The electromagnetic field produced around the coils is directly proportional

By assigning different WACC and FCFF‚ we determined that the emgs was worth $1266.85MM based on OHM information and $616.65MM using tech comparables. At last‚ we discussed the reason of the gap in value and why we thought it was more suitable to consider emgs as an oilfield service company. Warburg Pincus Warburg Pincus has a flat structure‚

two characters who have been enemies since birth. In the beginning of the story‚ Ulrich von Gradwitz‚ the protagonist‚ goes out to the forest even though it is not safe. Later in the story Ulrich has second thoughts‚ and wants to resolve things with Georg Znaeym‚ the antagonist‚ but nobody will know about it. Into the end of the story the two characters seek rescue‚ but from the sound of Ulrich’s laugh rescue is far away. Just by the given information‚ one can easily perceive how the author‚ Saki‚ uses

February 11‚ 2014 Academic English Assignment Mr. Gorman The Interlopers “The Interlopers” by H.H. Munro is a plausible story to which many can relate to‚ or will be able to at some point in life. The two main characters‚ Ulrich von Gradwitz and Georg Znaeym‚ were neighbours for years and who had hate in their family for generations. “Nature’s own violence overwhelmed them both” (p. 34)‚ describes how a tree came to fall on them both‚ while they were ready to harm or kill one other with guns in

them to a different conclusion. It starts with Ulrich von Gradwitz holding his rifle in the lands that were appointed to him by the Court. These lands were the cause of the feud that separated the two participating families. He waits for Georg‚ his life-long enemy‚ to approach him to face him. After they meet‚ they start an argument. While they were arguing‚ they don’t notice that a storm had begun; as a consequence a tree gets struck by lighting. This tree falls down‚ pinning both men‚

The characteristic of a resistor is a straight line‚ because voltage and current are proportional‚ through Ohms Law (V=IR or R=V/I). This equation shows that the slope is the value of the resistance which intercept at zero (line that passes through the origin). This information‚ along with a visual representation of it‚ is shown in the lab book with the visual
