PLEASE HELP For a particular transformer, the voltage E in the circuits is related to the number of windings W of wire around the core by the equation E=40W. How many windings will produce a voltage of 760 V? A voltage of 760 V will be produced by ? windings.

Solution: Here, we have the given equation in 2 variables where value of 1 variable is given so other can be easily calculated by putting the value of given variable in the equation.

So, Putting the value of E in the given formula and finding W, the number of windings:

[tex]760=40 \times W\\\Rightarrow W = \dfrac{760}{40}\\\Rightarrow W = \dfrac{76}{4}\\\Rightarrow W = 19[/tex]

So, number of windings for a voltage E = 760V is 19.

A voltage of 760V will be produced by 19 windings.
