Have a little read: ... Physics coursework yr10: Resistance of a wire Planning Aim: To investigate how the resistance of a wire changes Key factors: * Voltage across wire (higher the voltage, the faster electrons flow and the resistance does not change) * Current in circuit (higher the current the more electrons going through the wire, so more resistance) * Length of a wire (the longer the wire the more resistance) * Thickness of wire (the more thicker the wire the less the resistance there is) * Light dependant resistor (light intensity decreases the resistance increases) * Temperature (If temperature gets too high then wire could melt and if temperature gets too low then wire could snap). Prediction: I predict that the longer the wire, the higher the resistance. This is because if the wire is short the electrons will flow straight through and not bump/collide into each other, but if you increase the wire length the electrons have
