Factors affecting the resistance of a wire Introduction: Resistance is a force‚ which opposes the flow of an electric current around a circuit. Resistance is measured in Ohms. George Ohm discovered that a circuit sometimes resists the flow of electricity. He called this ’RESISTANCE.’ He even came up with a rule for working out the resistance of a circuit‚ which was: R= V ÷ I V- Volts I- Current R- Resistance Ohms law says the more resistance means more energy is needed for the current to

Aim: To investigate the factors that affect the resistance in a conductor. The main factors that affect the resistance in a conductor are: · Length · Temperature · Cross sectional area · Material · Magnetism The factor that we are going to change is the cross sectional area. Hypothesis: I think that the higher the cross sectional area‚ the lower the resistance in the conductor will be. This is because the Resistance in a metal conductor happens because as the electrons move through the material

Peaceful resistance has a positive impact on a free society. The best way to get things accomplished is to make your voice heard and to fight against topics you feel are unjust. However‚ the main component to being successful is keeping it peaceful. Too many times‚ people protesting get violent and take it too far. With the recent election of Trump‚ there have been riots with people harming others‚ burning buildings‚ and smashing windows. This has done nothing but make a common political party turn

Planning In this piece of coursework‚ I am going to investigate what affects the resistance of a piece of wire. Wire is made up of atoms. Electric current is a flow of electrons‚ and it is these electrons that collide with the nucleus of the atoms. Every time this happens‚ it causes resistance. The build up of friction is what produces the heat. There are many variables that could affect the resistance of the piece of wire: Length Potential difference Tension Temperature Diameter

What lessons about power‚ politics and resistance‚ in relation to organizational change‚ do you draw from this study? Resistance: Resistance to change is the act of opposing or struggling with modifications or transformations that alter the status quo in the workplace. Politics in resistance to change management - As based on the case study‚ it shows the confliction of interests and politics were the main reason deterring the necessary changes that should be implemented when the problem was identify

Bio-112 Antibiotic Resistance Experiment Lab Partners: March 10‚ 2010 When we initially started the bacteria antibiotic experiment on February 10‚ 2010 our team selected e-coli and Rifampicin (Rb5) to find out the level of resistance e-coli would build towards this antibiotic. When we first checked our agar dish on February 15‚ 2010 we noticed two circles for the zone of inhibition the small circle was 1.5 cm and the medium circle was 3.00 cm. Two days later when we checked

factors affect the resistance of a conductor‚ and the mathematical relationship that exists between these variables. Hypothesis Copper wires would be a better conductor than nichrome wires because it would yield less resistance when they have same cross-sectional area‚ length and temperature. Resistance would be increased when length wires increased. Resistance would be increased when cross-sectional area of wires decreased. Resistivity of wires is a factor of affecting the resistance.

or we hear it at school‚ resistance it seems to be happening more and more these days. Most of the resistance that I have seen‚ watched‚ or heard about lately has been centered around our new President‚ Donald Trump. Most of these protest or resistance to laws or resistance to change or even resistance to changing the laws‚ there have been no in-between on sides or passion. We have either seen peaceful resistance or an all outright very violent and destructive resistance. Both sides‚ peaceful &

Causes of antimicrobial drug resistance Microbes‚ such as bacteria‚ viruses‚ fungi‚ and parasites‚ are living organisms that evolve over time. Their primary function is to reproduce‚ thrive‚ and spread quickly and efficiently. Therefore‚ microbes adapt to their environments and change in ways that ensure their survival. If something stops their ability to grow‚ such as an antimicrobial‚ genetic changes can occur that enable the microbe to survive. There are several ways this happens. Natural (Biological)

What is peaceful resistance? We have seen many examples in history up even to today‚ in my case‚ even close to home. Peaceful resistance and non-violent protests is the practice of achieving goals through symbolic protests‚ civil disobedience‚ and noncooperation. The real question is with deaths of many great leaders and people throughout history with this "peaceful protest" is it a good thing? If you look at the outcomes‚ the positives outweigh the negatives. If colonial Indians hadn’t spoken-out
