Solved: The formula E = IZ, where E represents voltage, I represents current, and Z
Chapter 7, Problem 165(choose chapter or problem)
The formula E = IZ, where E represents voltage, I represents current, and Z represents impedance (a measure of opposition to a sinusoidal electric current), is used in electrical engineering. Each variable is a complex number.
In Exercises 161–166, use the formula to find the missing quantity for the given conditions. Then convert the given conditions to trigonometric form and check your result.
E = 12 + 24i
Z = 12 + 20i
