filament definition physics

filament Definitions and Synonyms. 5.10). Filament definition, a very fine thread or threadlike structure; a fiber or fibril: filaments of gold. They are graphical characteristics showing how […] • Explain the shape of this graph. Biology Dictionaries. Revise voltage and current in resistors, filament lamps, diodes, leds, thermomistors and transistors with BBC Bitesize GCSE Physics. This heats up when an electric current passes through it, and produces light as a result. As the temperature increases, resistance of the filament increases. It contains a thin coil of wire called the filament. The filament supports the anther, which is where pollen develops. Definition and synonyms of filament from the online English dictionary from Macmillan Education. 520 THEPHYSICSTEACHER Vol. Power is measured in Watts (W). A filament is topped by the anther. Filaments in incandescent light bulbs are made of tungsten. Fingerspell. As the temperature increases, resistance of the filament increases. It contains a thin coil of wire called the filament. Filament current A low current that passes through the filament to warm it and prepare it for the thermal jolt necessary for x-ray production. Power is the rate of using energy. A short filament, detected by identifying an alignment of star-forming galaxies, in the neighborhood of the Milky Way and the Local Group was proposed by Adi Zitrin and Noah Brosch. But when we see a filament in profile against the dark sky it looks like a giant glowing loop -- these are called prominences and they can be spectacular." Create an account; Learn / Biology / Intermediate Filament. Intermediate Filament Definition. Objectives: To be able to describe an experiment to obtain the I–V characteristics of a filament lamp and light-emitting diode (LED); To be able to describe the uses and benefits of using light-emitting diodes (LEDs). Define filament current. From the I/V graph, the ratio V/I increases as current increases. The stamen of a flower — the part that produces pollen — consists of a slender stalk, called a filament and an anther. The current flowing through a filament lamp is not directly proportional to the voltage across it. V / V I / A 3.0 0.6 4.0 0.75 6.0 1.00 8.0 1.20 physics the thin wire inside a light bulb. Filaments in incandescent light bulbs are made of tungsten. Quantum filaments can be hundreds of meters long, but have almost no mass, making them extremely difficult to detect. Filament definition is - a single thread or a thin flexible threadlike object, process, or appendage : such as. That is, the filament … That is, the filament … The resistance of a lamp increases as the temperature of its filament increases. Telescopes gather far more light than the eye, allowing dim objects to be observed with greater magnification and better resolution. The individual motor neuron plus and the muscle fibres it stimulates, in a combination is called a motor unit. 2. in an x-ray tube, the wire (cathode) that makes electrons available for interaction with the anode when it is heated to incandescence to form an electron cloud. Synonyms: Long and thin objects. This is the British English definition of filament. The intermediate filament is defined as the cytoskeleton structural components that are present in cells of vertebrates as well as invertebrates. (physics, astronomy) A massive, thread-like structure, such as those gaseous ones which extend outward from the surface of the sun, or such as those (much larger) ones which form the boundaries between large voids in the universe. This wire is called a filament. The filament is the part of the light bulb that produces light. When a flower opens, the filaments can be seen inside, thrusting up like stems within the flower itself. (ˈfɪl ə mənt) n. 1. a very fine thread or threadlike structure; a fiber or fibril: filaments of gold. Learn more. The apparatus was set up as shown in the diagram. ... a tetramer. 37, Dec.1999 Basic Physics of the Incandescent Lamp (Lightbulb) U ntil a little over a century ago, artif- i cial lighting was based on the emi- s sion of radiation brought about by burning fossil fuels—vegetable and animal oils, Filament. Ronaldo Degazon Saturday 03/11/12 Physics Lab #16 Electricity Aim: To investigate the IV relationship for a filament lamp. The filament LED difference Now that you know just what an LED is doing when it is producing light, we can get down to what makes a filament LED so different from your average LED. Reason: As the potential difference across a filament lamp increases, the current increases and the energy dissipated, as heat, increases, resulting in a higher temperature. In a typical 60-watt bulb, the tungsten filament is about 6.5 feet (2 meters) long but only one-hundredth of an inch thick. Resistance of a Filament Lamp In this lesson, we will • Describe the current/potential difference graphs for an ohmic conductor and for a filament lamp. line. It may also be known as the electron emitting element in a vacuum tube. .
