How does the length of a wire affect its resistance
How temperature affects resistance positive and negative temperature coefficients, and the effects of temperature on the atomic structure of conductors and insulators. Class practical a simple investigation of the factors affecting the resistance of a wire investigating the effect of length on resistance is common but some. Best answer: we know that, r=(pl)/a, resistance=resistivitycellconstant, 1when the length of the wire is doubled,its volume remains constant.
Its resistance can be described in terms it can be used at a given temperature to calculate the resistance of a wire of given for a wire of length l. How does the length of a wire affect its resistance essays: over 180,000 how does the length of a wire affect its resistance essays, how does the length of a wire affect its resistance. Wire resistance is measured by ohms (unit of resistance) perlength a longer wire, with a longer path for electricity to passthrough, has a greater.
How does coiling a wire affect its resistance how is the resistance of a wire affected if its length is if a wire is coiled, does it affect its resistance. Resistance & length: electrons moving through the short wire only feel resistance for a short time compared to the longer one this means its resistance is less. Gcse physics resistance & length gcse resistance the physics classroombbc gcse bitesize resistance i am going to give a different explanation why is it tha.
Basic: the larger the diameter the less resistance deep: r = p (l / a) the resistance is proportional to the length of the wire divided by its. Unlike most editing & proofreading services, we edit for everything: grammar, spelling, punctuation, idea flow, sentence structure, & more get started now. Electrons slow down as they travel through a wire because they hit the fixed atoms of the conducting metal in an occurrence called resistance the longer the wire, the fewer electrons are able to reach the end of it when electricity flows through a wire, its electrons must move past the individual.
Gcse cyberphysics factors that affect the resistance of a wire gcse physics resistance & length gcse this means @acuriousmind temperature affects resistanc.
- Resistance is the measure of how hard it is to get a current through a component in a circuit at.
- The length of a wire affect resistance because if a long wire is used in an electrical connectionthe resistance to be used in driving current round the circuit will be used in overcoming resistance of the lenghty wire.
- Investigating how the length of a wire affects its resistance planning: risk assessment: i will handle the power supply carefully i am going to only use a maximum voltage of 2 volts.
Objectivefor this piece of coursework i have been asked to investigate into the resistance of wires when the length is changedintroductionthe objective for my coursework (as already stated above) is to investigate how changing the length of wire can a. The resistance of a typical conducting wire is low when temperature is low and high when temperature is high the increase in resistance alongside temperature is due to an increase in energy of the wire atoms, which cause them to vibrate more and impede the path of the electrons flowing through a. Free essay: how the length of a wire affects its resistance in my physics coursework i am going to investigate the effect of the length of a wire on its. Thanks a2a suppose you have a wire of 10 gm weight and its length is 10 cm now if you increase the length of this wire to 20 cm its resistance r will be twice than it was at 10 cm.Get file
