How Does The Diameter Of Wire Affect The Resistance In A Circuit? Introduction: Some metals such as copper‚ silver and gold are very good conductors of electricity. This is because they all have only one electron on the outer shell. This means that they need only a tiny amount of energy in order to allow the electron to move. Non-metals‚ however‚ do not have free electrons‚ so even non-metals that only have one electron on their outer shell can still hold onto them tightly. Aim Of The Investigation:

What Is Resistance/Weight Training? Resistance/ weight training is any type of exercise that causes the skeletal muscles to contract and detract with the resistance of an outside force. This outside resistance can be produced in many ways‚ a few examples are: dumbbells‚ rubber exercise tubing‚ your own body weight‚ bricks‚ bottles of water‚ or any other object that causes the muscles to contract. A common name for this exercise is weight lifting. There are many different exercises that fall within

Introduction The resistance of a wire depends on certain factors. Some of these variables are listed below: Length of wire Diameter or thickness of wire Temperature at which wire is kept The material of which wire is made out of. The potential difference or voltage. Humidity Cross sectional area. Voltage across circuit All these factors will have to be kept constant except the diameter of the wire whilst doing the experiment to ensure that the investigation is

Current and Resistance Physics Investigation Aim: Investigate how the length of a wire affects the current and resistance of a wire. Prediction and Hypothesis: I think as you increase the length of the Constatan wire‚ you also increase the amount of resistance. The current is the flow of electrons; the current is dependent on the amount of voltage‚ which is applied. Voltage is the push given to the current. The current has to go through a circuit‚ which contains resistance so if you increase

DBQ #5: Slavery and Sectional Attitudes‚ 1830-1860 During the mid 1800’s many Americans began to have mix feelings over the issue of slavery. Many northern Americans believed that slavery was morally wrong and that it was an evil. Southerners on the other hand believed it was a good for the economy as well as for commerce. This great split of attitudes between the north and the south eventually led to threat of the civil war. The North saw the issue of slavery as an evil. They believed

DBQ # 6 Slavery and Sectional Attitudes One effect on the issue was that the economy in the south was fueled by cultivation of staple crops that required slaves for labor. In the South slavery wasn’t thought as an evil as in the North because to the Southerners defense the slaves in their opinion were treaty in contrast to workers in England and peasants that were Irish‚ also the end of slave trade brought higher value to the slaves causing their owners to be less harsh because they were more valuable

different areas‚ and especially in the making of ships. The surface area that is touching the water of the ship is very large‚ due to the shape of the hull‚ and that‚ beside the density of the ship‚ is what keeps the ship floating. An important example of how surface area affects buoyancy is when people float in the water. Everyone knows that it is much easier to stay afloat when we are lying on our backs than when we are in a standing position in the water. But how does the surface area of an object

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

OBJECTIVE For this piece of coursework I have been asked to investigate into the resistance of wires when the length is changed. INTRODUCTION The objective for my coursework (as already stated above) is to investigate how changing the length of wire can affect the resistance. There are factors which can affect how accurate our expriment is come on four levels. As in any scientific experiment‚ there are always variables ( "likely to change or vary subject to variation; changeable." ) which can
