circuit analysis and design‚ play a massive role in electrical engineering and without the correct application of theory and practise in unison‚ nothing can be achieved in a true engineering sense. Engineering requires theory to develop and test constraints while also requiring practical application of theory in order to determine tolerance and practical results for industry purposes. The ability to analysis a circuit gives a potential electrical engineer the ability to learn how to problem solve

The basic of simple electrical circuits and measurements is learned. Also‚ investigating the dependence of the resistance of a wire on its length‚ cross-sectional area‚ and the material of which it is made. By examining electrical resistance (R) through a metal conductor‚ the voltage (V) and current (I) through the conductor‚ the following principles will be demonstrated: 1.) Ohm’s Law 2.) Dependence of resistance (R) on the length (L)‚ cross-sectional area (A) and electrical resistivity (ρ) and

proportional to the source acting in the circuit. This is also known as Linearity. The proportionality constant (K) relates the input voltage to the output voltages as Superposition is another way to solve a linear electrical circuit. The Superposition Theorem states that in any linear electrical circuit‚ any voltage or current value can be obtained by taking the individual contributions to that voltage or current as a result of each source taken alone and summing them together Aim The aim of this

ELECTRICAL SUBSTATION A substation is a part of an electrical generation‚transmission and distribution system. Substations transform voltage from high to low‚ or the reverse‚ or perform any of several other important functions. Electric power may flow through several substations between generating plant and consumer‚ and its voltage may change in several steps. Substations may be owned and operated by a transmission or generation electrical utility‚ or may be owned by a large industrial or commercial

This circuit employed the output from an uncomplicated light/dark activated circuit and oblige a relay in its output which can be further attached to switch ON/OFF a street light and electrical application in a household also. Many of the people have a phobia of darkness‚ so to assist them in such situation‚ we have explained a simple circuit . It will automatically turn on street light in the way of LED’s or bulb coupled with relay‚
