Question

4. Answer the following question: 3x1=3 4.1 The ratio of the lengths of two wires is 2:1 and the ratio of their radii is 1:2. Calculate the ratio of the resistance of the two wires if their resistivity is in a 3:4 ratio.​

Answer 1

Answer:

6:1

Explanation:

$resistance = (resistivity) \times l \frac{1}{\pi \times {r}^{2} }$

3×2/1² :4×1/2²

6:1
