How the Length Affects the Resistance of a Wire

How the length affects the unsusceptibility of a wire Introduction designing In this piece of coursework I want to find bulge out how the length affects the justification of a wire. What is electricity? Electricity is a form of energy. The go down of negatrons is the tend of electricity. Every oneness thing is made up from subatomic particles. In the centre of the atom there is a effect. Inside the nucleus there are two polar types of particles. Positively super hinge ond particles called protons dead particles called neutrons. The nucleus of the atom is surrounded by some opposite type of particles. These particles are called electrons. Protons safekeeping is usually equal to the neutrons charge and the heart of protons inside the atom usually is equal to the kernel 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 flow of electric current (or the flow of electrons) running through it. We quantity resistance in Ohms ? essentially electrical resistance is near enough equivalents to friction that occurs in a mechanical system.

You would get an infinite current if you were to expend a electromotive force to current with zero voltage. All currents move over ca-ca some resistance which limits the current. Remember this equation: V= I x R Relationship between Resistance, voltage and current. A current always consi st of 3 different quantities. electromot! ive force (V) Current (I) Resistance (?) These 3 quantities make up Ohms Law. I will be using these in my sample to measure the resistance of the wire. My Prediction I predict that the steadfast 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.
