How the Length of a Wire Affects its Resistance

Think about the situation you have two lights that have different is this resistance is and both are connected via wires in series with an electrical sore switch in our case is a battery. One of the lights close very brightly, all the other light is very dim, and if it even is blowing, there's a chance that is not. With our knows that we know as of now and physics, we know that the current will flow through both of the bulbs, and it will not matter which the voltage flows through first, that it will all add to the total voltage in the battery in the end. But why is it that one of the batteries glows so much better than the other? The first thing that we must at determine, is what it was the thing that chooses the brightness of the bulb, and is it due to

a) Enter the following command in R to read a simple help page about the length() command:

Introduction: Voltage can be thought of as the pressure pushing charges along a conductor, while the electrical resistance of a conductor is a measure of how difficult it is to push the charges along. Using the flow analogy, electrical resistance is similar to friction. For water flowing through a pipe, a long narrow pipe provides more resistance to the flow than does a short fat pipe. The same applies for flowing currents: long thin wires provide more resistance than do short thick wires. The resistance (R) of a material depends on its length, cross-sectional area, and the resistivity (the Greek letter rho), a number that depends on the material. The resistivity

Copper is used in various industries including: Building Industry – 47%, Transportation – 10%, Consumer Products – 11%, Electronic Products – 23% and Industrial Machines – 9%. Copper is an extremely good conductor, which is why it is produced and used in forms of copper wire, cabling, generators, motors and various other appliances. Copper’s resistance to corrosion means it can be used in areas containing moisture such as water piping and tanks, plumbing, and also in hot water systems which is effective due to its suitable heat conduction. It is easy to form shapes such as pipes with copper due to its malleability. Copper also has the ability to lose heat very quickly, which makes it an effective element to be used in air conditioning and heat exchangers.

Determine the mole ratio-the ratio of the number of moles of silver to the number of moles of copper. Note: Round the results to the nearest whole number

1. Consider eight two-cubic centimeter (2 cm3) sugar cubes stacked so that they form a single 2 x 2 x 2 cube. How does the surface area of the single, large cube compare to the total surface area of the individual eight cubes? Report your answer as a ratio. Be sure to show all calculations leading to an answer.

As you increase the resistance the flow of the electrons in the battery also slow down. IF the resistance is strong than the current flow is also slower. The blue spheres also move slower because of high resistance. The voltage for the battery is independent of the resistance. The temperature of the resistor increases as the resistance is decreased. The green particles are also increased when the resistance is higher.

The preferred hand data has 50% of its results in a range of 2.6 cm, thus indicating that the results were quite consistent as 50% of the results occurred in the range of 15-17.6 cm. Whilst the rest of the data was quite spread quite as the minimum was 8.6cm and the maximum was 21.6 cm, which is a range of 13 cm. Therefore the rest of data had been spread evenly as seen in the boxplot and

2. Carefully straighten the steel paper clip. Use the wire clippers to cut it to the same length as your copper wire.

How can the times of the copper wire wrapped around the nail would affect the strength of the magnet? Hypothesis My hypothesis for this experiment is that the more copper is wrap around the nail the stronger will eventually be and the more heavy things can hold and lift . Also the thickness of the wire will affect the strength.

For the middle segment, it is seen that the piece started out being 4.9 mm. After one day, the piece grew 0.1 mm. The piece stayed approximately the same size until Day 4, where it grew to 6 mm. No gradual changes were seen between Days 1 and 3. The size of the middle segment changed again on Day 6, where it was 6.1 mm. The segment was the same size for the next 2 days. The middle segment grew to 6.2 on Days 9 and 10 (Figure 1). Overall, the segment grew 1.3 mm.

When tested in the lab, it was found that Advance Wire was mediocre in conductivity & abrasiveness, while also being heavier than all other samples.

Background Students had been taught ‘Electrochemistry’ as outlined in the IB Chemistry syllabus. Investigation Design an experiment that allows you to investigate a variable affecting the rate of electroplating. Your research question must be focussed and specific and must enable you to carry out your experiment safely and within the allocated time. Safety Show your research question to your teacher. Complete a safety hazard assessment before writing a full plan (a + b). Ensure your teacher approves this. Experiment If your plan is safe you will be allowed

Throughout this research paper, the reader will have a better understanding of the different forms of resistance. Also the reader will have the ability to compare the two types of resistance which were active and passive. And finally the reader will be abl
