Junction Reports Samples For Students

Introduction

Alternative renewable energy continues to grow popularity because of the upsetting climate change caused by greenhouse gases, exhaustion of non-renewable energy resources and rising global demand for energy. Renewable resources of electricity production are vital progress and are fundamentally motivated by cost.
Solar energy is clean and profuse that is why it is the best among the available substitutes. The modern solid-state photovoltaic (PV) technology began in 1954 upon the discovery of silicon (Si) diodes photovoltaic effect . Crystalline Si and a wide range of thin film solar cells, which are inorganic, are the prevailing photovoltaic technologies employed nowadays .

Part 1. Solar Panel History

The history of Solar panels takes it beginning from the 7th Century B.C. Now, the energy sector of economy has the greatest impact on our lives. Power supply is the basis of the normal functioning of any production, and, consequently, the entire human civilization. Heat and light homes, work machines and units in production, traffic and rural suffering - all these many faces of Energy. Various technological advances have already become part of life for us, but they are possible only when adequate and affordable energy supply, due to the development of alternative energy sources, ...

Lab Report: Common Emitter Amplifier

Introduction

A laboratory was conducted to evaluate the characteristics of a common emitter amplifier. The configuration is a bipolar-junction-transistor (BJT). Transistors allow current to flow from positive to negative states or from negative to positive states. A transistor board was supplied for the experiment. Five activities were done during the lab: a DC analysis, An AC analysis gain at midband (with bypass capacitor in circuit), AC analysis gain at midband (with no ...

Lab Report (Kirchhoff’s Laws)

Introduction
This lab experiment was intended to learn and apply Kirchhoff’s Rules in calculating the current and voltages in a circuit. To achieve this, a circuit is built consisting of resistors that are in parallel and series which will aid to test the different aspects of Kirchhoff’s Rule.

The simplest circuit is that which can be reduced to an equivalent circuit having a single resistance

and a single voltage source. Many circuits are not simple and require the use of Kirchhoff’s

Laws to determine voltage, current, or resistance.

Objectives:
forecast by Kirchhoff’s Laws.

Theory:

A junction is a point in a circuit where more than three wires join or where a current gets divided.
A loop is a path which is closed by two ...

Use of Fossil Fuels for Power Generation and the Need for Renewable Energy

According to Nelson (2011), more than 85% of the world’s energy consumption, which is estimated at 520 exajoules, is generated through the burning of fossil fuels such as petroleum, natural gas and coal (p.19). Electric power generation from non-renewable sources will, unequivocally, result in their exhaustion and creation of a major energy crisis. For this reason, it appears primordial to shift in a greater scale to alternate power generation, such as solar, wind, hydroelectric, etc. Amongst these, Sorensen (2011) explains that though hydroelectric power does represent one of the major forms of power generation, its growth is stagnant ...

Feasibility Study on Solutions to efficiently power an electrical vehicle
Abstract
“Feasibility Study on Solutions to Efficiently Power and Charge Electrical Vehicles”
The future of electric vehicles needs to shift toward the use of solar charging stations which can increase the feasibility of electric vehicles outside of urban areas. The solar powered charging stations can revolutionize the way the world views vehicles powered by renewable energy sources. These solar stations can be placed in rural areas which can allow the drivers to store and charge their vehicle, which will minimize the prevalence of vehicles being stranded without access to ...

Abstract

An operational amplifier – OP-AMP is a circuit device that amplifies buffers or attenuates the input signal depending on the configuration. Amplified signal means that the output is greater than the input. This means the gain is larger than one. A buffered output means that the magnitude of input is equal to the output; only that the input has been delayed. An attenuated signal implies that the gain magnitude is less than unity. In this paper, amplification using an op-amp will be investigated. Inverting and non-inverting configurations will be connected and tested. Input waveforms and output waveforms will be compared. It ...

Cut Off Region of a Transistor

The transistor goes into the cutoff region when the base current (IB) is equal to zero. The collector leakage current ICEO under such conditions is quite low due to the effect of thermally-generated carriers. This means that ICEO can be neglected in the circuit analysis such that VCE will be equal to VCC. During the cutoff region, both the base-collector and the base emitter junctions are reverse biased. Subscript CEO means a representation of the collector to emitter with the base open. This is represented in the circuit below.

Saturation Region of a Transistor

Forward biasing of the base-emitter junction increases the base current. Consequently, ...

1.0 Introduction

On 11th December, 2005 a series of explosions occurred at Buncefield oil storage depot leading to massive losses in both commercial and residential property therefore this report addresses the case study of Buncefield; it also explains and gives reasons for the mitigation measures I recommend that the public and private sector organizations can employ to avoid a re-occurrence of such an incident. Some of the measures are: control and safety systems for petroleum storage, land use planning and control of societal risks around major hazard site, protection against loss of containment and also constant review on the maintenance and replacement policy ...
