that boosts the battery ’s 12 volts to as high as 20‚000 volts. The incoming 12 volts of electricity pass through a primary winding of about 200 turns of copper wire that raises the power to about 250 volts. Inside the distributor‚ this low-voltage circuit is continuously broken by the opening and closing of the points‚ each interruption causing a breakdown in the coil ’s electromagnetic field. Each time the field collapses‚ a surge of electricity passes to a secondary winding made up of more than a

problem. You may also not know that you use the scientific method to solve lots of everyday problems. It has become so simple to use that it is done every day. Even if you simply solved this problem by changing the light bulb or checking the circuit breaker box the scientific method was employed in some way. Step one of the scientific method is observation. The first thing I would do is look and see if there are other electronic devices off. Based on the observations you make you can determine

INTRODUCTION Automated Greenhouse is about a design of miniature greenhouse that is equipped with the automated monitoring system. The system will constantly monitor the natural environmental conditions in the greenhouse to ensure that the plant will achieve the maximum plant growth. There are two sensors‚ which operate in the real-time‚ that will be used - temperature sensor and a humidity sensor to monitor the conditions. The microcontroller will compare the output of the sensors with the preset

ABSTRACT The manual method of synchronization demands a skilled operator and the method is suitable for no load operation or normal frequency condition. under emergency condition such as lowering of frequency or synchronizing of large machines a very fast action is needed‚ which may not be possible for a human operator. Thus there is a need of autosynchroniser in a power station or in an industrial establishment where generator are employed. This paper describes a microprocessor based set

Operating hours vary throughout the summer‚ but on most days the park opens at 10:00 a.m. and closes at 10:00 p.m. Guests of the on-site hotels (Hotel Breakers‚ Sandcastle Suites‚ Lighthouse Point‚ Camper Village‚ Breakers Express and Castaway Bay) are granted 1 hour early access to the park. In 2009‚ Cedar Point will be open daily from May 16 through September 7‚ then on Fridays‚ Saturdays‚ and Sundays from September 18 through November

protection against the dangerously high levels of electricity that is being delivered to the home. Each circuit is protected by a circuit breaker‚ or fuse in older homes. When a problem occurs with the electrical current such as a short‚ or the current reaches an unsafe level as in an overloaded circuit‚ the breakers are designed to turn off‚ which cuts off the electrical current to the affected circuit. This helps to prevent overheating‚ fire and potential
