Investigating Whether the Surface Area or the Length of the Carbon Putty Will Affect Its Resistance

Investigating whether the surface area or length of the putty will affect its resistance plan It is investigating whether the length or surface area of ​​the putty affects its resistance. From A. F Abbott 's general physics book, it is known that conductor resistance is affected by several factors.

The purpose of this survey is to investigate the relationship between resistance and conductive putty and to understand how the length of putty affects this relationship. Experiment: Conductive putties were specifically designed as conductors; this was accomplished by adding carbon black. Since it is conformable so that cross-sectional area, length and shape can be easily changed, this can be easily used to demonstrate the concept of resistivity. This experiment shows the effect of resistance in the circuit as the putty length becomes shorter. Every time 5 cm, 30 cm putty is used.

Is wire resistance dependent on its length? A survey was conducted to answer this question, but is wire resistance dependent on its length? To answer this question, observe the experiments and results to prove whether wire resistance depends on its length. For this experiment, the equipment used was a 1 m long nichrome wire, copper alloy, voltmeter, ammeter, alligator clip and battery pack. Record voltages and currents of different lengths when the device is attached

Physical factors that affect the resistance of conductors are constants according to the material called length, cross-sectional area, and resistivity. Because the resistance per unit length along a uniform wire is the same, if resistances of wires of different lengths are found, the resistivity can be calculated.

Once you know the resistivity, cross-sectional area and length of the sample material, you can calculate its resistance. Resistance, R = resistivity, p (? M) x length, l (m), or R = pl (?) Cross-sectional area A (m 2) A Then, what do you know about resistance? Why do you want to experiment? Let's examine how wire length affects resistance. Apply the same voltage to the same wire of the same length and investigate the influence of that length on the resistivity. The longer the wire, the higher the resistance is expected.
