Use a more precise meter for measuring resistivity of the samples.
scientist is logical and systematic they are willing to improve each experiment
Regarding the question of "Why isn't there voltage drop in a 240 volt system?" The smart alex answer is "because no current is flowing." Only if no current is flowing can there be no voltage drop in any circuit. All conductors, even supercondutors, have resistance and this resistance will produce a voltage drop when a current is flowing through the conductor(s). 240 volts is used over 120 (or 12 volts) because it reduces the current reguired for a fixed amount of POWER (watts). Therefore, the conductor size can then be reduced to reduce cost, size, weight or to improve flexibilty.
It is the salt solution and distilled water
sweet potato potato cucumber lemon that's all i know for now but i am doing my research for a science fair project...if u have anymore please improve this question. I just did a science fair project with my son and a potato was not a conductor of electricity.
Yes. On a scale of 0 to 100, where annealed copper is 100, aluminum rates a 59, and brass averages 28. I say averages because there are actually quite a few different alloys of brass, but all of them are poorer conductors than aluminum.
It is the addition of impurities to a semi-conductor in order improve their electrical conductivity.
u could improve it by not forgetting to repeat it.
it is by repeating the experiment a few times which make the results more reliable
repeating it
To improve the power factor
some of them do use science experiment maybe to improve their movies but some don't it maybe they don't know how do the experiment works.
A variable test?
Ioniser

In an evaluation you put what you need to improve on the next time you do an experiment.
Phosphorus increases electrical resistance so it would negatively effect current efficiency in the electro chemical process of smelting aluminum. That is why Phosphorus is not used in primary production of aluminium. The process of taking refined bauxite (alumina) and turning it into pure aluminum uses an enormous amount of electrical power so any reduction of electrical resistance can improve efficiency and save a great deal of money.
work harder or take a good advice from your boss. to improve your performance in your current jobs.
