conveniently designed conductive disks allow the electrical load of the generator to be fed either with alternating current or direct current. the loop terminals is sinusoidal with zero mean value (Fig. 2). Its frequency is equal to the number of revolutions per second executed by the loop. Each terminal of the loop is connected to a metallic ring. The contacts with rings are made by means of fixed brushes. If the brushes are connected to an electrical load‚ an alternating current will be established

Assigned Task 9 - Hazards and risks Briefly describe a situation in your care work when you have recently been involved in an activity with a child that involved either: moving and handling (such as a wheelchair) hazardous and non-hazardous equipment and materials (such as a craft session‚ cookery group‚ assisting someone with hygiene needs or administering medication). Any setting or activity carries a level of risk. By identifying and reducing risks in advance‚ full use can be made of the setting

the field is given by the direction of that force. Electric fields contain electrical energy with energy density proportional to the square of the field amplitude. The electric field is to charge as gravitational acceleration is to mass and force density is to volume. 1. Suppose that two point charges‚ each with a charge of +1.00 Coulomb are separated by a distance of 1.00 meter. Determine the magnitude of the electrical force of repulsion between them. Given: Q1 = 1.00 C Q2 = 1.00 C

this Unit I will explain potential hazards and the harm that it can cause. A hazard is any source of potential damage‚ harm or adverse health effects on something or someone under certain conditions at work. Basically‚ a hazard can cause harm or adverse effects (to individuals as health effects or to organizations as property or equipment losses). Sometimes a hazard is referred to as being the actual harm or the health effect it caused rather than the hazard. Hazards include: * Slippery floors

Moral Hazard A few years ago when Hurricane Katrina wake‚ many people fled the ravaged Gulf Coast were spending disaster relief paid for by taxpayers‚ on tattoos‚ expensive handbags and making trips to their favorite places. In this case the damage has already done and people are using the debit cards issues by FEMA (Federal Emergency Management Agency). The debit cards are issued to buy the necessities like food and clothing. But the damage was done and people misused its money. FEMA swore that

wide variety of natural and human-induced hazards and disasters. Phenomena such as floods‚ extreme wind speeds‚ earthquakes‚ mudslides‚ droughts‚ wildfires‚ pest plagues‚ air and water pollution cause extensive losses to livelihoods and property‚ and claim many lives. This study attempts to bring to light disasters or hazards‚ there examples‚ as well draw attention to the challenges faced by the government of Zambia in controlling the disasters or hazards and Conclude with suggested possible solutions

affordable and reliable‚ have flexibility of control‚ and offer significant electrical energy savings through greatly reduced electric bills. They are used in a wide variety of applications for various reasons. For example‚ they are the most effective energy savers in pump and fan applications; they enhance process operations‚ particularly where flow control is involved. VFDs provide soft-start capabilities‚ which decrease electrical stresses and line voltage sags associated with full voltage motor start-ups

course is divided into two categories: ‘Services’ and ‘Safety and Emergency’. The Safety and Emergency training course is to ensure all cabin crew members are aware of the safety hazards on board‚ how to avoid any risks of health and safety hazards‚ and are well-trained to handle any emergency that might occur. Hazards cabin crew members may face include: Psychological - Sexual harassment: female flight attendants are a target for sexual harassment from passengers on board. This may cause stress

inspiring and interesting talk; entitled “HAZARD OF SMOKING”. DEFINITION FROM WIKIPIDIE A hazard is a situation that poses a level of threat to life‚ health‚ property‚ or environment. Most hazards are dormant or potential‚ with only a theoretical risk of harm; however‚ once a hazard becomes "active"‚ it can create an emergency situation. A hazard does not exist when it is not happening. A hazardous situation that has come to pass is called an incident. Hazard and vulnerability interact together to
