INTRODUCTION Electricity is usually invisible. Except for lightning and sparks, you never see it in daily life. However, light bulbs and a magnetic compass can show you when something electrical is happening. By observing their behavior and making a few assumptions, you can begin forming ideas about electricity. This type of thinking is called “building a model”. INVESTIGATION ONE: WHAT IS NEEDED TO LIGHT A BULB? 1.1 Activity: Lighting bulbs in a loop Insert three D-cells into the battery holder (as in Figure 1.1), and insert two ROUND bulbs (not long bulbs) into a pair of sockets. Use three wires to connect the sockets to each other and to the two “terminals” of the battery holder: 1) the spring inside the case near the red spot, and 2) the metal post on the outside of the case near the blue spot. The bulbs should light and be of similar brightness. The battery, bulbs and wires now form a “closed loop”.…
Ans: Electricity is the movement of electrons. As long as electrons in an atom are balance and revolve precisely in orbit around their sun or atom nucleus there is no electron flow or electric current in a wire. These atoms are the smallest particle into which an element can be divided without losing its property. A single atom consists of three basic components: a Proton, a Neutron and an Electron. An atom is similar to a small solar system, so is the nucleus in the centre of an atom. Protons and neutrons are contained within the nucleus. Electrons orbit around the nucleus which could be similar to planets orbiting around the sun. As an electrician I will also be dealing with insulators. An insulator is any material that stops the flow of electrons examples are rubber, glass and plastic. Conductors are the opposite of and insulator they are material that easily allows electrons to flow, like cooper, gold and silver. A material that has high resistance has low conductivity, this means that it doesn’t conduct current easily; likewise a material that has high resistance has high conductivity. Resistance is measured in units called Ohms. There are types of electricity, one is static electricity. Static electricity is the charges that are fixed in place unlike electrons in wires with voltages potential with no electron flow. Opposite electrical charges always attract each other, so these particles with opposite charges will tend to move towards each other. Like electrical charges always repel.…
Every year, hundreds of citizens and construction workers are either killed or hurt by power lines. Electricity columns on the streets are extremely dangerous; the power lines often hit each other and create an electricity shock and cause a lot of damage to people and birds and houses nearby. These power lines also often fall on the ground due to heavy wind or storms which leads to a lot of damages and might cause a big fire and even leads to the death of many. Also the overhead power lines can cause a lot of cancerous diseases due to the high amount of electricity circulating around it.…
These place a duty on employers to assess all foreseeable risks associated with work activities involving electricity. Employers are required to install safe systems of working, with well-maintained equipment, covering everything from power lines to kettles. All installation and repairs should be undertaken by a qualified electrician or those who have appropriate technical knowledge, though some minor repairs, inspections, fitting of plugs, etc may be undertaken by suitably trained staff.…
Electricity is all around us, no matter where you work there are electrical outlets and machines that run off electricity. Due to how dangerous electricity can be Occupational Safety and Health Administration or OSHA has come up with safety standards when dealing with electricity. Their standards are designed to protect employees who are exposed to the dangers whether it be directly like working on an outlet or indirectly like using the outlet. Safety equipment is available for the safety of the people working with electricity.…

The electrical equipment that is operational in the working environment also poses some threat and hazard to the people handling the equipment. There are chances of electric shock and burn injuries, electrical shorts and fire, or even electrocution. In order to prevent electrical accidents from occurring, it is essential for the equipment to be inspected on regular basis, and moreover, any equipment that is…

Abstract- In this few years some of employer complaint towards the awareness of fresh graduate regarding background of electricity in Malaysia. They cannot figure out the company profiles and person in charge for electricity in Malaysia, a few of them do not know about the Electricity Rules and Regulation in Malaysia. A number of engineers does not follow the rules and regulation and hence cause accidents to occur especially on electrical. This report is going to describe on the replacement company of electricity in Malaysia, the Electricity Supply Act 1990 as well as the Electricity Rules and Regulation 1994. Keyword – Electrical Supply Act 1990, Electricity Rules and Regulation, Replacement Company, Case study: DC-10 flight…
Electricity is one of the basic needs of every individual especially in this “digital” era wherein technology has taken place. It is important in houses, streets, mini-stores up to big companies. With it, we enjoy lighting for our home, and heat and cooling to keep ourselves comfortable, and access to the countless appliances that make our lives better. By powering television and computers, it keeps us in touch with the outside world, and by powering alarms and security systems, it keeps our homes and our families safe. Without it, we’d literally be in the dark. And yet despite its importance, we often take our electrical wiring for granted. When properly installed, an electrical system will provide years of service, but wear and tear always take their toll, and problems still arise from time to time. However, it is everyone’s responsibility to make sure that it is properly installed to ensure the safety of everyone. Faulty wiring is one of the causes of fire which commonly occurred in Mangagoy, Bislig City where most of the students of University of Southeastern Philippines-Bislig Campus resides.…
