node voltages of both planar and non-planar circuits. Nodal equations are usually formed by applying Kirchoff’s Current Law to the nodes with unknown voltages‚ whereas equations based on Kirchoff’s Voltage Law are used to form the mesh equations. In order to apply nodal analysis to a circuit‚ the first step is to select a reference node or datum node and then assign a voltage at each of the other nodes with respect to the reference node. In a circuit with dc sources‚ the node that has the lowest

LED Flasher Circuit Project Overview : This project involves the design‚ documenting and building of a LED flasher circuit controlled by a software program written in the C programming language. The hardware circuit consists of a PIC 16F684 microcontroller‚ ten LEDs with resistors ‚ and two switches. Software Program The software program will read the settings of the two switches. If both switches are off‚ the LEDs are all off. Any other switch settings will start the LEDs flashing in a unique pattern

Generator reactances are used for two distinctly different purposes. One use is to calculate the flow of symmetrical short circuit current in coordination studies. A second use for generator reactances are in specifications that limit the sub-transient reactance to 12% or less in order to limit the voltage distortion induced by non-linear loads. For either short circuit or harmonic distortion analyses‚ the stated reactances will need to be converted to a common base to make valid comparisons. Typically

Third generation (1966-1973) computer consisted of integrated circuits (IC) i.e. many transistors in single silicon chip. A single IC has many transistors‚ registers and capacitors built on a single thin slice of silicon. With the invention of microprocessor (1971)‚ fourth generation of computer evolution started
