How the Length of a Wire Affects Its Resistance In 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. Current is the rate of flow of charge through a conductor‚ and it is measured in amps using an ammeter. To help me plan my investigation I have completed a preliminary experiment in which I investigated the effect of the thickness of a wire on its resistance‚ using

How Does The Legnth Of A Wire Affect Resistance In A Circuit? Physics Investigation Aim: To measure how the length of a wire affects the amount of resistance when an electrical current is passed through it. Background Information: What is an electrical current When a full circuit is created (i.e. a continuous loop has been made connecting the negative end of an electrical source to the positive) it creates a path for electrons to pass through. These electrons need a "push"

Does peaceful resistance affect our laws positively or negatively? In fact peaceful resistance has a positive impact on our laws. Just like publicity‚ non-violence is supposed to lower the bars of negative effects‚ impacting our laws. The relationship between the american public and laws enforcement has always‚ had a violent nature that as a country has never been able to escape. Yet‚ throughout the years the people of this country have used peaceful resistance to change so much of the mistakes‚

* I will make sure I have a clear space to work in and nothing on the floor around me. In this investigation‚ I will set up a simple circuit to be able to read the voltage and current when the length of wire changes‚ so I then can work out the resistance. I will be using constantan wire starting of with 1m length and then decreasing it by 0.10m intervals down to 0.20m long. I will not go above 1m or below 0.20m because it may be too long that they resist so much current that the wire burns‚ or the

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. Background

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 Shape Material of the wire I have

Peaceful resistance to laws positively affects a free society. Since we’re Americans we’ve been learning about American History since we started school. Breaking the law is not always a bad thing. IF the law goes against something you believe in ‚ and you know it’s not right break the law. Yes‚ if you’re caught you’ll be jailed but it’s worth it to stick up for something that you believe in. Take for instance in the Civil Right’s Days when Rosa Parks was fed up with the unequal treatment blacks received

Diabetes is a chronic disease that affects the endocrine system‚ and occurs when your blood glucose‚ also known as blood sugar‚ is too high. Disease is a very common and serious disease that affects approximately 29.1 million people in the U.S.‚ let alone the 86 million people that have prediabetes‚ without even noticing it‚ (MedicineNet.com). To understand diabetes‚ it is important to understand the role of insulin and glucose in the body. Glucose‚ or sugar‚ is an important source of energy for
