Physics coursework - Does the length of a conduction putty affect its resistance? Hypothesis: I predict that as the length of the conducting putty increases, its resistance will increase. This is because as the length of the conducting putty increases, the current will have to pass through more molecules of the element(s) that the conducting putty is made of. This will make it harder for the current to pass through the conducting putty and so the electrons that compose the current will collide with more of the elements that make up the conducting putty. This causes friction between the electrons and the molecules and so heat is dissipated, which makes the circuit less efficient. This means that the putty is acting restricting the flow of electrons around the circuit more efficiently as its length increases, hence it is a better resistor. In order to calculate the resistance of the wire, I plan...
