Electric Field X 2
1,267 words... n line 3. Place the plates at 5 cm apart, using the set square making sure that the plates are 2. 5 cm form the centre line. 4. Turn on the EHT 5. Raise the voltage to 1 kV 6. Use the 10 second count, move the GM tube until there is a drop in the background count. Change to 100 s and move the GM slightly until you just get a back group count. 7. Record this result in the table. 8. Repeat step 5 to 7 increasing the voltage by 1 kV Analysis This experiment is similar to an electron gun experim...

Electric Charge Electric Field
972 wordsElectric Water Heater And Piezoelectric Force Transducer Electric Water Heater And Piezoelectric Force Transducer What is a piezoelectric force transducer (or sensor)? A transducer is a device that transmits power from one system to another. In the case of the piezoelectric, they power comes in the form of electricity from a piezoelectric material acted on. Piezoelectricity may be described as the property of some materials that become electrically charged when subject to mechanical stress. Thes...

Speed Of Light Lightning Bolt
3,469 wordsElectricity Electricity WHAT IS ELECTRICITY Electricity is a form of energy. Thats because we can use electricity to do things for us, like run machines and computers. Electricity also can be transformed into other types of energy such as heat or light and is used to heat our homes, light our cities and towns and power the computers we are using. Electricity is the type of energy that is invisible. Its made of moving electrons that are so small and move so fast that we cannot see them. The elect...

Charged Particles Electric Charge
1,314 wordsJ. J. Thomson Science lecturers who traveled from town to town in the middle nineteenth century delighted audiences by showing them the ancestor of the neon sign. They took a glass tube with wires embedded in opposite ends... put a high voltage across... pumped out most of the air... and the interior of the tube would glow in lovely patterns. In 1859 a German physicist sucked out still more air with an improved pump and saw that where this light from the cathode reached the glass it produced a f...

Valence Electrons Electric Field
1,130 wordsSolar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products. Photovoltaic cells work effectively even in cloudy weather and unlike solar heaters, are more efficient at low temperatures. They do their job silently and there are no moving parts to wear out. It i...

Speed Of Light General Theory Of Relativity
3,151 wordsI. Introduction 1. Theory of Black Holes Black holes are one of the least understood phenomenons in the galaxy yet the secrets contained within the black hole could revolutionize the field of physics. Black holes are formed when an enormously massive star, most likely a neutron star, collapses in on itself. This happens because when the star dies all the energy generated from the sun s fusion reaction that was formerly pushing outward suddenly stops. When the outward force stops, the sun has so ...
