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.

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

Step-by-step explanation:

Given the equation:

E = 40W

Where E is the Voltage in the circuits

and W is the number of windings

Given that E = 760V

To find: W = ?

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:

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

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

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
