Bitesize resistance in a wire
Did you know?
WebFor example, when the length of the wire is 20 cm, the resistance is 3.14 ohms; when the length of the wire is 40 cm, the resistance is 6.18 ohms, which is roughly double. In my main investigation, I will see if this observation applies to my results. WebThere are several factors that affect the resistance of a conductor; material, eg copper, has lower resistance than steel length - longer wires have greater resistance thickness - smaller...
