ABSTRACT Flood is one of the disastrous phenomena that caused a lot of deaths to some other uninformed area in the province. The researchers from Negros Occidental High School proposed a study with the objective to construct and develop a flood detection device‚ present a practical device‚ and introduce the device to a certain residents in the province that needs to be aware of flood. After the device was constructed‚ the researchers tested the device in a cup of water. During the testing of device

PRINCIPLE OF GENERATION‚ TRANSMISSION AND DISTRIBUTION OF HIGH AC VOLTAGES INTRODUCTION The potential benefits of electrical energy supplied to a number of consumers from a common generating system were recognized shortly after the development of the ‘dynamo’‚ commonly known as the generator. The first public power station was put into service in 1882 in London (Holborn). Soon a number of other public supplies for electricity followed in other developed countries. The early systems

First I am going to explain what a circuit is and what the differences they have are. An electric current is a flow of charge. The charges are given energy and made of flow using a cell or a battery. Charges can flow easily through connecting wire. The cell‚ wires‚ lamp and a switch‚ all these components are connected together and make a loop called a circuit. Current will only flow through a component if there is a voltage across that component. Voltage is the driving force that pushes the current

CHAPTER ONE INTRODUCTION A. STATEMENT OF THE PROBLEM This study aims to find out how long a lemon (Citrus limon) can last as a lemon battery powering a digital clock. B. HYPOTHESIS The researcher assumes that one lemon would last for a day or two and that the usage of more lemons would entail a longer battery time. C. OBJECTIVES Specifically‚ it aims to: 1) come up with a quantity-longevity ratio with the use of a varied quantity of lemons in the production of a lemon battery 2) find

on. A circuit is a system that is made of three different components and they are: an energy source‚ a load or resistor‚ and a conducting wire‚ but there is the option to use a switch. Each component has a different role in a circuit. An energy source is the source of the energy‚ the load or resistor is what uses the electricity‚ the conducting wire is what connects the circuit‚ and if you use the option of a switch you can stop the flow of electrons from going through the circuit. If one of

’Was general haig the butcher of the Somme?’ Introduction General Haig’s title of ’butcher of the Somme’ originated after the First World War‚ when‚ due to a large number of casualties Britain suffered from the war and mostly the Somme. The people of Britain wanted someone to blame. This was a coping mechanism in which people could deal with the loss of the ’lost generation’. Feild Marshall Haig has often been called the butcher of the Somme because 20000 soldiers died on the first day of the battle
