Ques-1: What is a transformer and how does it work? Ans: A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. A transformer has no moving parts and is a completely static solid state device‚ which insures‚ under normal operating conditions‚ a long and trouble-free life. Construction of transformer is very simple‚ two or more coils of insulated

Current and noncurrent assets There are two main categories that assets can fall in‚ and those are current assets and noncurrent assets. Assets are valuables such as cash‚ inventory‚ trademarks‚ and property. Current and noncurrent assets differ from one another in several ways. The main difference among current assets and noncurrent assets is the time it takes for them to liquidate when needed. The order of liquidity is presented on the balance sheet in the order of the amount of time it takes

Measuring the Resistivity of Copper Wire of Different Lengths In this report I will be writing about the experiment I will conduct on copper wire of different lengths. The dependent variable I will be measuring is the resistance of the Copper wire. To do this experiment‚ one needs to obtain measurements with a high degree of accuracy‚ taking care of the equipment they use and measuring each value to a certain degree of accuracy for all results. The problem with measuring the resistivity of Copper

Move the compass slowly along a semicircular path above the bar magnet until you’ve put it on the opposite side of the bar magnet. Describe what happens to the compass needle. The white lead of the needle faces the South part of the magnet in a perpendicular way. When the needle is facing the center of the magnet‚ the lead turns to a 90 degree angle

multi-meter and compared to the calculated values‚ and the measured percent error in the measurements were found to be within 1 percent error. 1.0 Introduction Kirchoff’s Current Law (KCL)‚ and Ohm’s law are use to find the three node-voltages‚ vA‚ vB‚ and‚ vC‚ of the given circuit (See Figure 1 below). KCL uses node currents and then applies Ohm’s law to derive an equation in terms of node voltages‚ resistors‚ and source voltages. These two laws are only needed when there is: known resistors‚
