How the Length Affects the Resistance of a Wire

How the length affects the unsusceptibility of a wire Introduction repoint In this piece of coursework I want to find fall out how the length affects the electric resistance of a wire. What is electricity? Electricity is a form of energy. The go down of negatrons is the tend of electricity. Every wiz thing is made up from instalments. In the centre of the atom there is a effect. Inside the nucleus there ar two diverse types of particles. Positively super hinge ond particles called protons negatroneutral particles called neutrons. The nucleus of the atom is surrounded by some some other type of particles. These particles are called electrons. Protons trip out is usually equal to the neutrons charge and the heart of protons inside the atom usually is equal to the fall of electrons. An Atom may gain or lose an electron when an outside force aggravates the balancing force between the protons and electrons. (Add in about collisions in a wire look at page 131 in physics textbook) What is Resistance? Electrical resistance is how a material opposes to the go down of electric current (or the flow of electrons) running through it. We quantity resistance in Ohms ? basically electrical resistance is near enough equivalents to friction that occurs in a mechanical system.

You would get an infinite current if you were to utilise a potentiality to current with zero voltage. All currents post ca-ca some resistance which limits the current. Remember this equation: V= I x R Relationship between Resistance, voltage and current. A current always consist of 3 different quantities. electromotive force (V) Current (I) Resistance (?) These 3 quant! ities make up Ohms Law. I will be using these in my experimentation to measure the resistance of the wire. My Prediction I predict that the perdurable wires will have bigger resistance. I think this because in a longer wire the electrons will have more than collisions making it harder for the electrons to expire through. Variables that could affect my experiment....If you want to get a full essay, holy order it on our website: OrderEssay.net
