Investigating the resistance of wires - Practical Physics Class practical A simple investigation of the factors affecting the resistance of a wire. It's not all about the collision with the edges of the path.
I'm guessing that an alloy of iron and aluminum is cheaper than one with a very high percentage of nickel and some chromium, and that for the service involved with a flame rod, that Kanthal is the best material with the longest service life available.

The purpose of this study is to examine the effect of teachers' error feedback on. In the context of your analogy, the highway is always full of cars. Take care to avoid short-circuiting the coil by using a wooden lolly stick or spatula as the stirrer.
Record marks by task.
A super crest is followed a short time later as a supertrough and so over time, the effect is big. The pattern was explained in terms of path difference between one point and source one, and the same point and source 2. I looked into a few different factors, including; Heat of the ball, la If electricity costs 10 cents per kWh, how much does it cost to run the computer annually?

All teachers check, mark, and return homework.Go to Wikipedia and look up “Resistivity.” In the table contained in the article you’ll find the risistivity of nichrome is *10^-6 ohm-meters.
For any nichrome wire you have in mind, multiply this resistivity value by the length of the wire and divide by the cross sectional area of the wire. The resistivity of nichrome is Ω · m and its Im doing my resistance of a wire coursework. If a wire is longer why does the voltage increase and the current decrease?
physics A potential difference of 12 V produces a current of A in a piece of copper wire. What is the resistance of the wire?
2 Introduction You have already carried out an experiment to determine the resistivity of a metal wire. You are now going to assess the reliability of your experimental value for the resistivity and suggest how.

Nichrome is commonly wound up into coils and used in heating elements (devices that convert heat into electricity through Joule heating) such as hair dryers, toasters and ovens.
However, nichrome wires are not used as much as copper wires (resistivity = × 10 −8 Ωm) due to the high cost of chromium.Download
