AT105 8 December 2006 "Ohm’s Law is the relationship among electric current‚ resistance‚ and voltage. The principle is named after the German scientist George Simon Ohm." Webster’s Online Dictionary. I will be discussing the uses of Ohm’s Law and why it is so important in everyday electrical problems whether it be simple or not. It is everywhere and used by many whether they notice it or not. Ohms law states that current in amperes is equal to voltage divided by resistance. This form of ohms

increase. So due to complexity‚ it is very difficult to draw the Bewley Lattice Diagram beyond certain time period. But with the presence of simulation packages we can simulate any number of substations transient behavior for any time duration. Current values of substations are shown following figures‚ At substation

Steps 1. Facts: * Raintree must maintain a current ratio of at least .9 in order to maintain the terms of the debt agreement in place with the bank. If Raintree fails to do so‚ the cost of borrowing from the bank will likely increase. * Raintree company controller‚ Jackson Phillips‚ estimates that the 2013 year-end assets and liabilities will be $2‚100‚000 and $2‚400‚000 respectively. This scenario would put Raintree’s current ratio at .875‚ .025 lower than the required benchmark

Explain how you proved Kirchhoff’s Voltage Law. I was able to verify the system as a closed loop and the voltage across the resistors totaled the total voltage supplied. 5. What would happen to the current IT if one of the resistors like R3 is Short-circuited by chance? Will the current‚ compared to the original

2. Dual-loop Control of a Grid-Connected Inverter In this section‚ the modeling and control of a grid-connected inverter with dual-loop control using the capacitor current feedback is described. Although‚ this issue has already been addressed in available literatures‚ the goal is introducing a simplified block diagram which make designing controllers easier. A grid-connected inverter with the LCL filter is shown in Fig. 1. The LCL filter consists of an inverter-side inductor L1‚ a filter capacitor

magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object‚ but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current which may be either alternating current (AC) or some form of direct current (DC) (rectified AC).
