WebA ductile metal wire has resistance R. What will be the resistance of this wire in terms of R if it is stretched to three times its original length, assuming that the density and resistivity of the material do not change when the wire is stretched? (Hint: The amount of metal does not change, so stretching out the wire will affect its cross-sectional area.) WebTo investigate how changing the length of the wire affects its resistance. Method connect the circuit as shown in the diagram connect the crocodile clips to the resistance wire, 100...

WebFor a given material,the resistance and length formula clearly speaks that the resistance is directly proportional to its length. When the length of the material is increased, its value … WebThis will give me the resistance of the wire in ohms. 5) I will repeat the original test for 100cm a further two times, giving me a set of three results. I will then find the average of these results by calculating the mean. 6) I will then repeat the experiment for wire lengths of 20cm, 40cm, 60cm, 80cm, 150cm, 200cm, 250cm and 300cm. pops in a box

WebFurthermore, the resistance of a wire is directly proportional to the length and inversely proportional to the area, so doubling the length of a wire should increase the resistance … WebNov 18, 2016 · 37K views 6 years ago Electricity This physics tutorial explains how the resistance of a wire depends on its diameter. The larger the diameter, the more paths there are for charge carriers... WebJan 23, 2024 · What is the effect of increasing the length of the wire in a single circuit? But increasing the length of the wire increases its resistance and reduces the current for the same potential difference (voltage), per Ohms law V=IR. The work per unit charge in moving the charge along the length of wire does not change unless there is a change in ... pops in a way crossword clue
