Assuming in a closed circuit, will the length of wires affect the brightness of a bulb please answer as detailed as possible thank you. Extension cords deliver power when product cables can't reach an electrical outlet consider the cord length along with the wire gauge.
There are a few factors that affect how much resistance electricity encounters, including the width of the wire, the wire material and the length of the wire a longer wire requires more width and should be made of a material that is highly conductive to cut down on resistance. Does it get lower or higher when the length of the wire increases. How do you find the length of a wire when given the wire's density, diameter, and mass the density if 896g/cm3 the diameter is 25mm.
Gcse cyberphysics factors that affect the resistance of a wire gcse physics resistance & length gcse this means @acuriousmind temperature affects resistanc. The size of wire is directly proportional to the voltage drop allowed and the length what this means is that if your wire is rated for 20 amps at 100 feet you’re allowed a 3% voltage drop if you double that length your size of wire needs to double in area (not to be confused with gauge) to retain that same voltage drop. Assuming the wire is made of copper, poisson's ratio is about 355, which is the ratio of strain in the cross sectional area to strain along the length of the stretched copper wire without considering poisson's ratio, one would expect the area of the cross section to be halved, and the final volume to remain constant, but this would be wrong. Re: weight to length with copper wire not exactly sure what you are after, but it would be different for each guage of wire, but you have the density of each so it would be easy, just different.
[solved] investigating the effect of magnetic force on a current carrying wire 1 the length of the wire and the strength of the magnetic field constant. Free essay: how does the length of a wire affect its resistance introduction: this first report in physics will show the investigation of how the length of. Definition: the calculation or measurement of the length of the wire used to make a helical coil spring.
How the length of a wire affects its resistancein my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance is the measure of how easy it is for current to flow through a wire. Mark, the short answer is: the longer the wire, the larger the resistance more detail: resistance is a measure of how difficult it is to push electrons (the particles that carry electrical current) through a wire the larger the resistance, the more force you have to apply and. For example, when the length of the wire is 20cm the resistance is 314 ohms when the length of the wire is 40cm the resistance is 618 ohms, which is roughly double in my main investigation i will see if this observation applies to my results.
Best answer: we know that, r=(pl)/a, resistance=resistivitycellconstant, 1when the length of the wire is doubled,its volume remains constant. We commonly hear, “what’s the maximum thermocouple wire length i can use with your instrument” that’s a good question there are two factors that affect tc cable length:. Class practical a simple investigation of the factors affecting the resistance of a wire apparatus and the thickness of the wire, its length and the. Gcse physics resistance & length gcse resistance the physics classroombbc gcse bitesize resistance i am going to give a different explanation why is it tha.
Two wires of the same material are both connected to a 9-v ideal battery they have the same cross section area but wire 2 is twice longer than wire. The length of the wire will be changed by moving the crocodile clip across the wire on a ruler the independent variable will be the length of the wire because that is what i will be changing the dependant variable will be the resistance because it will change only due to the length of wire. Figure out the length of each circuit, using your home's floor plan how to estimate the amount of wire needed to rewire an average home home guides. Wire has a certain amount of resistance as electricity flows down the wire, some of the voltage is lost in the wire before reaching the lamp.Download
