An Investigation Into The Resistance Of A Wire Gcse Physics Coursework Planin this investigation i am going to investigate how the length of a piece of wire affects its resistance. the following are all variables that affect the resistance of the wire: the thickness of the wire is a big variable as the thinner the wire t. The aim of this investigation is to reveal that the factor of length affects the overall resistance. so when changing the length of the conductor does resistance increase or decrease. prediction. i predict that as the length of the wire decreases so will the resistance. this is because through a shorter length of wire would allow more current.

Resistance Of Wire Investigation Length Writework 3. measure out the different lengths of wire. 4. carry out experiment with shortest piece of wire. 5. record amp and volt readings. 6. repeat experiment using other lengths of wire. 7. record amp and volts for each experiment. 8. work out the resistance of each piece of wire and right in a table. equipment: * nichrome wire * power pack * meter. Table 1: preliminary results. these results show that as the length of the wire increases, the resistance increases, as well. furthermore, if you double the length of the wire, the resistance is roughly doubled. for 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. Plot a graph of resistance against length for the resistance wire; results. some example results may be: length (cm) potential difference (v) current (a) resistance (Ω) 100: 1.20: 0.16: 7.5: 90:. Procedure. connect up a series circuit of two cells, and the ammeter, with a 30 cm length of one of the wires closing a gap between two crocodile clips. note the reading on the ammeter. replace the specimen of wire with another of the same length but different gauge or material. investigate how the current depends on the thickness of the wire.

Use the equation \(v=ir\) to calculate the resistance of this length of wire. repeat steps 4 and 5 increasing the distance between the clips by an interval of 10cm a further 5 times. plot a scatter graph with the length of wire on the x axis and the resistance on the y axis .
