How the Length Affects the Resistance of a Wire

How the length affects the unsusceptibility of a wire Introduction bewilder In this piece of coursework I want to find off how the length affects the opponent of a wire. What is electricity? Electricity is a form of energy. The go down of negatrons is the tend of electricity. Every star thing is made up from segments. In the centre of the atom there is a effect. Inside the nucleus there argon two contrasting types of particles. Positively super hinge ond particles called protons drained particles called neutrons. The nucleus of the atom is surrounded by some some other type of particles. These particles are called electrons. Protons vex is usually equal to the neutrons charge and the heart of protons inside the atom usually is equal to the nub 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 13 1 in physics textbook) What is Resistance? Electrical resistance is how a material opposes to the emanate of electric current (or the flow of electrons) running through it. We quantity resistance in Ohms ? fundamentally electrical resistance is near enough equivalents to friction that occurs in a mechanical system.

You would get an infinite current if you were to apply a potency to current with zero voltage. All currents afford 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 diffe rent quantities. electromotive force (V)! Current (I) Resistance (?) These 3 quantities make up Ohms Law. I will be using these in my look into to measure the resistance of the wire. My Prediction I predict that the abiding wires will have bigger resistance. I think this because in a longer wire the electrons will have to a greater extent collisions making it harder for the electrons to expire through.
