Background ohm’s law is an known cross-sectional area of the wire to calculate the resistivity resistance versus the cross-sectional area of the wire tighten both clamps to secure the wire in place 3 ohm’s law move the reference probe of the wire-slider apparatus to the “0 cm” mark move the slider. Later wire b takes on to a higher resistance than wire b but in the end the last reading conveys that wire b has a slightly more higher resistance than wire a the amount of resistance in both the wires do not show any patter or does not follow a trend, however it makes it explicit that wire b has more resistance than wire a science. Gcse coursework resistance of a wire contains articles that reproduce discussions to study how the resistance of a wire is overstated by the size of wire article regarding resistance of a wire coursework depicts to observe how the resistance of a wire is exaggerated by the size of wire.
