Have you ever wondered about what kind of fuel is the cheapest? With the way people seem to be switching to more electric cars over gas, I wanted to compare the two. I feel, that there has been more technology in electric cars within the last 5 years than there has been in gas cars in the last 10 years. The factors we will need to consider when comparing electric cars to gas cars consist of convenience, cost of electricity/gas, […]
In the world of electrical engineers it is not easy to define or analyze any system performance without any proper study. Every electronics system is defined in terms of mathematical equations. I am keen to study about radio frequency circuits. In these systems it is always necessary to know how much error is obtained and we need to estimate the error so that we can design the system that can be used efficiently. Also the signals that are received in […]

Two algorithms for modeling the loads are introduced and compared, based on sampling and one based on statistical distribution build from the sample database. Simulation of load versus time was performed using a horizon of 7 days using both techniques. The cause for the difference in the result of these two approaches is explored. Regardless […]
Our daily energy needs are increasing every day at exponential rates, with an increase from 51,000TWh to 150,000TWh in the span of half a century. If this current trend continues with 80-85% of our total energy needs being derived from non-renewable resources such as coal and crude oil and with these said to run out in 110 years (coal) and 54 years (natural gas), we desperately need to look for new renewable sources of energy and save what we have […]
The wind is one of the oldest naturally occurring phenomenon on planet Earth, coming into existence at the beginning of time. Since its been here, there have been numerous amounts of uses for the wind, with an emphasis on wind power. Since the beginning of written history, and perhaps even before, it has been recorded that the wind has played a serious, impactful role in the history of mankind. For instance, wind energy propelled boats along the Nile as early […]

Wind strength (or wind power) indicates the system by way of which wind is used to create electricity. Wind generators convert the kinetic power in the wind into mechanical power. A generator can alter mechanical power into electricity. To obtain wind power, the kinetic energy of wind is used to create mechanical power. A generator converts this energy into electricity so that it may also be used for the gain of mankind. Recently, extraordinary types of electrical energy era have […]
Albeit today viewed as an elective energy source, wind power is perhaps the soonest type of energy collected by people. Wind is brought about by the lopsided warming of Earth’s surface, and its energy is comparable to about 2% of the sun based energy arriving at the planet. The measure of energy hypothetically accessible from wind is in this manner, exceptionally incredible, in spite of the fact that it would be neither down to earth, insightful, nor important to catch […]
Wind power has been utilized by individuals since forever and changed over into usable energy. Little windmills have been giving capacity to country homes all through the world since just about 100 years prior. They were utilized for controlling water siphons and furthermore changed over wind into useable power for homes. In the 1930’s, projects to carry power to more distant regions stretched out the electrical lattice framework to these spaces causing windmill produced ability to step by step be […]

Power factor: The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load to the apparent power, and is a dimensionless number between 0 and 1 (frequently expressed as a percentage, e. g. 0. 5 pf = 50% pf). Real power is the capacity of the circuit for performing work in a particular time. Apparent power is the product of the current and voltage of the circuit. Due to […]
Transistor A transistor is a semiconductor device used to amplify and switch electronic signals. It is made of a solid piece of semiconductor material, with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be much more than the controlling (input) power, the transistor provides amplification of a signal. Today, some transistors […]

INTRODUCTION 1.0 INTRODUCTION Private branch exchange system (PBXs) operates as a connection within private organizations usually a business. Because they incorporate telephones, the general term “extension” is used to refer to any end point on the branch. The PBX handles calls between these extensions. The primary advantage of PBXs was cost savings on internal phone calls: handling the circuit switching locally reduced charges for local phone services. The private branch exchange (PBX) provides internal station-to-station communications for a well-defined set […]
Gas prices are going up. We realize this is an obvious statement because you buy gas and you pay attention. But maybe you aren’t paying as much attention as you thought you were. Did you realize that gas prices have gone up 46% in the last year? A year ago, gas prices were at $1.96 on average, nationwide. A year later, prices sit at $2.86 per gallon. The problem is, we’ve become so used to gas prices in the $3/gallon […]
