Investigate The Factors Which Affect The Resistance Of A Piece Of Resistance Putty
Investigate the factors which affect the resistance
Of a piece of resistance putty
Planning:
This investigation is designed to look into the resistance of different materials, in this case, resistance putty in the form of wires, and their conducting capability in different shapes. We must bear in mind though that different thickness and length of the putty used to make up the wire itself will affect the electric conduction capability. Therefore, the factors are;
The thickness of the putty e.g. 1mm, 2mm, 3mm in diameter or 1 cm in diameter
And also
The length of the putty e.g.25cm, 50cm, 75cm long.
The experiment will require both the readings of voltage and current in order to produce the value of resistance according to the formula;
putty, resistance, current, voltage, length, wire, experiment, through, across, readings, constant, long, conductor, 2cm, using, proportional, wires, longer, because, recorded, power, placed, piece, law, give, directly, time, prediction, ohms, off, graph, ends
