Calculating the Length of Wire in Two Coils

To calculate the length of wire in the first coil when it is half the length of the second coil, we can use a simple mathematical relationship.

Let's denote the length of wire in the first coil as x and the length of wire in the second coil as y.

According to the given information, the length of wire in the first coil is half the length of the second coil, so we have the equation:

x = (1/2)y

Now, we need to find the value of x in terms of y.

Solution

Using the given equation x = (1/2)y, we can express y in terms of x as follows:

y = 2x

This means that the length of wire in the second coil is twice the length of the wire in the first coil.

Therefore, if the length of wire in the second coil is y meters, then the length of wire in the first coil is x = (1/2)y meters.

So, if the length of wire in the second coil is 10 meters, the length of wire in the first coil would be (1/2) * 10 = 5 meters.

This calculation is based on the given relationship between the lengths of wire in the two coils.
