  1. General Physics II Lab (PHYS-2021) Experi…

    Resistance of the Length of a Wire at a Constant Temperature. The aim of this experiment is to investigate how the length of a wire at a constant temperature affects the resistance of electrical circuits. Variables: Independent variable = Length of resistance wire, L. …

  2. Required Practical: Investigating Resistivity

    Worked example. A student wants to find the resistivity of a constantan wire. They set up the experiment by attaching one end of the wire to a circuit with a 6.0 V battery …

  3. EXPERIMENTS EXPERIMENT 111

    Study the effect of diameter of wire on its resistance when its length is kept constant by using different SWG (standard wire gauge) wires available in the market.

  4. An Investigation Into the Resistance of a Wire: GCSE ...

    What Affects the Resistance of a Wire? In this article, I will investigate what affects the resistance of a wire. Electricity flows in metals. Metal wires are made of millions of …

  5. Core Practical 2: Investigating Resistivity

    A student conducts an experiment to find the resistivity of a constantan wire. They attach one end of the wire to a circuit that contains a 6.0 V battery. The other end of the wire is attached by a flying lead to the wire at …

  6. Resistance in a Wire

    Observe changes to the equation and wire as you play with the resistivity, length, and area sliders.

  7. Resistance (of a wire) || Experiments

    In this experiment, you can vary the effective length of a wire by moving an electrical contact and then go on to measure the wire's electric resistance by measuring potential difference and electric current on analogue dials. Press …

  8. Investigating the resistance of wires

    Students should come to understand that the resistance of a wire depends on its length, its cross sectional area, and the material out of which it is made. With some students you could go further and introduce the concept of resistivity ρ, …
