Sign in, choose your GCSE subjects and see content that's tailored for you. The current flowing through a filament lamp is not directly proportional to the, Home Economics: Food and Nutrition (CCEA). pinched filaments). fil•a•ment. A fine or very thin thread or fiber: filaments of cloth; filaments of flax. filament Definitions and Synonyms. Voltage is a representation of the electric potential energy per unit charge. If a unit of electrical charge were placed in a location, the voltage indicates the potential energy of it at that point. It contains a thin coil of wire called the. ... a tetramer. CSEC Physics Lab - IV Relationship of a filament lamp 1. Together the anther and filament make up the flower's stamen. The definition of a filament is a slender fiber or thread. It contains a thin coil of wire called the filament. This thin wire is called filament. In physical cosmology, galaxy filaments are the largest known structures in the universe. They are graphical characteristics showing how […] A negatively charged metal cup in which the filament is embedded that electrostatically confines the electron beam to a small area of the anode. If that were done in the open air, in the presence of oxygen, the metal filament would burn up before it got that hot. As the temperature increases, resistance of the filament increases. Definition: The metal resistance wire inside a bulb which transfers electrical energy to light (and heat). The word filament is from the Latin word filum, which means "thread." Definition. Color is a function of the human visual system, and is not an intrinsic property. Filament. The teardrop elongates until a tail of ink, called a filament, stretches away like the tail of a comet. light bulb (incandescent): 1 bulb containing gas, 2 filament, 3 connecting and supporting wires, 4 … Spectral power distributions exist in the physical world, but color exists only in the mind of the beholder. 520 THEPHYSICSTEACHER Vol. dimmer. That is, the filament … (ˈfɪl ə mənt) n. 1. a very fine thread or threadlike structure; a fiber or fibril: filaments of gold. filament [fil´ah-ment] 1. a delicate fiber or thread. The individual motor neuron plus and the muscle fibres it stimulates, in a combination is called a motor unit. Filamentation (or filamentary structure) is often seen in plasmas.It is created because plasma contains free electrons, making it highly electrically conductive — even more than metals, and even in tenuous cosmic plasmas.As charged particles readily move in a plasma, a ring of magnetic field forms around the current that can pinch it into filamentary current strands (ie. Revise voltage and current in resistors, filament lamps, diodes, leds, thermomistors and transistors with BBC Bitesize GCSE Physics. Define filament current. 1 A practical physics textbook states that “measurements may give a precise value for the ... 4 A student set up the circuit shown and measured the current I through the filament lamp for a range of values of potential difference (p.d.) Similar to the the resistor, or wire, at a constant temperature, a filament bulb shows the same characteristics in the negative quadrant (with the ratio of p.d. To make the bulb produce more light, the filament is usually made of coils of fine wire, also known as the coiled coil. This heats up when an electric current passes through it, and produces light as a result. Class 6 Physics Electricity and Circuits: Electric Bulb: Electric Bulb. An electric bulb is a device which produces light when electricity is passed through its terminals. 2. the stalklike portion of a stamen, supporting the anther. 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, Our perception of color is not an objective measure of anything about the light that enters our eyes, but it correlates pretty well with objective reality. Right : In 1999, extreme ultraviolet cameras on board the orbiting Solar and Heliospheric Observatory captured this image of a prominence above the eastern limb of the Sun. length. The filament is the part of the light bulb that produces light. to current varying with the same pattern). Filament could mean: In physics and electrical engineering: Electrical filament; Current filament; Filament propagation, diffractionless propagation of a light beam; In astronomy: Galaxy filament; Solar filament, a structure in a solar corona; Birkeland current; In biology: Protein filament; Filamentation, a … The apparatus was set up as shown in the diagram. Create an account; Learn / Biology / Intermediate Filament. ... physics the thin wire inside a light bulb. It contains a thin coil of wire called the filament. This lesson is about filaments, the structural proteins of the cell. Intermediate Filament Definition. Actin protein is the main component of the thin filament. This heats up when an electric current passes through it, and produces light as a result. Filament lamp. 5.10). Synonyms for 'filament': line, strip, stick, pole, length, thread, string, strap, spring, picket, pillar, plume, pointer, rail, ribbon, rod, spike A slender or threadlike structure or part, especially: a. 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. The reality of this filament, and the identification of a similar but shorter filament, were the result of a study by McQuinn et al. I-V characteristics I-V characteristics were introduced in the previous page when introducing Ohm’s law. Thin Filament: Thin filaments are made up of three proteins. Filament Definition from Science & Technology Dictionaries & Glossaries. More Lessons for IGCSE Physics Math Worksheets A series of free GCSE/IGCSE Physics Notes and Lessons. Whenever an electric current goes through the filament, the filament glows. Each actin protein has a tie ability for a myosin cross bridge. Biology Dictionaries. The tungsten is arranged in a double coil in order to fit it all in a small space.
