Collector Reports Samples For Students

Introduction

Solar heaters have been popularized in recent years for use in tertiary and residential areas. This has happened mostly in the third world countries. The reason behind this encouragement to use solar heaters is the reduction of cost and improving the performance. This has necessitated the use, and testing of solar heaters to produce hot water. The solar heater is fundamentally made up of tanks that act as solar absorbers ad storage bases for warm water. This is used in glazing to profit the green house effect and the insulating cases. The solar heaters can be made from ordinary ...

1. Introduction
Agriculture and other food products are dried for use. The agriculture grains are dried for future use or production process, in order to dry the agriculture products the sun drying has been used for many years. The sun drying dries the products in a open air condition with the help of hot sun rays. In past centuries the sun drying systems has been used. Most of the industries use mechanized drying instead of sun drying system. The mechanized drying uses boilers and fan to heat and force the air to the required part. The time taken for ...

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, ...

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 ...

Discussion:
Discuss the application of common collector transistor circuit.
The common collector configuration of the BGJ amplifier is mostly commonly employed as buffer or emitter follower. The voltage gain of the common collector amplifier is nearly unity and provides large current amplification. It is used in applications where current sourcing is required without modifying the voltage. The input resistance is quite high so it draws negligible current from source. Moreover, the load circuit will not interfere ...

Recommendation Report: Dish/Engine Type-The Best Concentrated Solar Power Technology

Introduction
The sun has provided the earth and everything in it with immense energy for years, and lots of these energies are left untapped. Even with the unprecedented advancement in technology today, only a little solar power is tapped. The studies reported that the side of the Earth having facing towards the Sun, a square kilometer at the outer edge of the atmosphere gets solar power up to 1,400 ...

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 ...

Introduction

A voltage stabilizer is an electronic gadget found in most of the circuit board of home electronics. A voltage stabilizer can be found in computers radios phone chargers and also DVD players. This important gadget comprises of diodes, capacitors, transistors, resistors and a step-down transformer. The work of a voltage stabilizer is to provide a steady current to the electronic equipment for it to function efficiently. A simple model of a voltage stabilizer looks like the diagram below. Symbols have their usual meaning.
In the above diagram, a step-down transformer reduces 240V of alternating current to around 10V of alternating current at the ...

1.The Aston-Martin Brand
1.1. History
Aston Martin Lagonda Limited, more commonly known by the name Aston Martin, is a British automobile manufacturer that is currently owned by the American Ford Motor Company. The company is quite old—it was founded in the early days of the automotive industry, in 1913, and became famous for unusual and exotic cars through the use of the automobiles in a number of James Bond franchise films (Cooper, Schembri, and Miller 2010; Aston Martin 2016). Aston Martin has changed hands a number of times; the company has always remained a luxury automotive brand, however ( ...

Introduction
A multiplexer is a crucial digital circuit that is capable of selecting a single digital signal out of a set or group of signal at its input and passes that signal to its output. It functions as a more as a rotary switch that switches connects one input to the output at a time. On the other hand, the multiplexer does the exact opposite function; it passes multiple digital signal inputs through one of a set or group of outputs. Through multiplexers, several signals can be sent ...
