Explanation:
The given data is as follows.
Resistance (R) = 1200 ohm, Area (A) = m (as
)
Diameter (d) = 2.3 mm = m
First, we will calculate the length as follows.
R =
Here, = resistivity of aluminium =
Putting the given values above and we will calculate the value of length as follows.
R =
1200 =
L =
As the circumference of circular wire =
or, =
=
And, number of turns will be calculated as follows.
No. of turns × Circumference = Length of wire
No. of turns ×
=
Thus, we can conclude that turns of wire are needed.
