Check the explanation
Explanation:
Kindly check the attached image below to see the step by step explanation to the question above.
Convergent boundary I think
1 x 10⁻¹¹m²
Explanation:
Given parameters:
Resistivity = 100 x 10⁻⁶Ohm.m
Cross-section = 1mm²
Resistance = 10ohm
Unknown:
length of the nichrome wire = ?
Solution:
To find the length of the nichrome wire, we use the expression below:
L =
where l is the length of the wire
R is the resistance of the wire
A is the area
p is the resistivity
Now we need to convert area from mm to m;
1000mm = 1 m
1mm² = 1 x = 1 x 10⁻⁶m²
Input the values in the formula;
L = = 1 x 10⁻¹¹m²
