An example of this is voltage = current x impedance
The number used for impedance is a complex number composed of a real number plus an imaginary number.
V=I*(R+J) voltage =current times impedance J is an imaginary number to make the math come out right.
Current is plotted horizontally on a graph and an imaginary vertical axis is used for j; a2 +b2 = c2 pythagorean theorem is used to calculate a value for the current. Showing that the imaginary number represents another dimension acting on the current. This imaginary axis, for the imaginary number, on the graph, is at a right angle to the real axis for the current. So the imaginary number is acting, mathematically, as another dimension.
Einstein's general relativity theory, to explain gravity, (which has been proven experimentally correct) uses time as a 4th dimension. In the real world the 3 dimensions, length, width, and depth are each one at a right angle to the other two dimensions. Time, being a 4th dimension, should be at a right angle to the 3 physical dimensions, to qualify as a 4th dimension. The imaginary number, used in calculating current and other things, has an imaginary axis on a graph that is at a right angle to the real axis, and it is therfore acting as a 4th dimension. Since the only proven 4th dimension is time:
I recommend that time should be substituted for the imaginary number in all calculations, in scientific disciplines, that use an imaginary number to make the math come out correctly.
This could lead to all sorts of new equations in all of these fields, and show how time itself is entering into the function of the real world in these scientific disciplines.
Could lead to seeing how time influences every science that uses imaginary numbers. Could (maybe) give a mathematical link between general relativity, [gravity] and electromagnetism, through substituting time symbols that represent time in each discipline into the other discipline. - Perhaps leading to a way of using electromagnetism to influence gravity.
Might even lead to a unified field theory that works.

This substitution for the imaginary number being time is already done in relativity theory:
Relativity
In special and general relativity, some formulas for the metric on spacetime become simpler if one takes the time variable to be imaginary.
Since the universe is uniform I recommend:
SUBSTITUTE TIME FOR THE IMAGINARY NUMBER, IN EVERY SCIENTIFIC DISCIPLINE THAT USES AN IMAGINARY NUMBER TO MAKE THE MATH COME OUT CORRECTLY.
See what new equations that it leads to and do experiments to verify if those equations accurately show what happens in the real world.

Since complex numbers provide a system for finding the roots of polynomials, and polynomials are used as theoretical models in various fields, complex numbers enjoy prominence in several specialized areas. Among these specialized areas are engineering, electrical engineering and quantum mechanics. Topics utilizing complex numbers include the investigation of electrical current, wavelength, liquid flow in relation to obstacles, analysis of stress on beams, the movement of shock absorbers in cars, the study of resonance of structures, the design of dynamos and electric motors, and the manipulation of large matrices used in modeling. While many of these applications are beyond the scope of the Math B curriculum, an introductory glimpse of the application of complex numbers to electrical circuits can be easily understood and manipulated by students.
Application to Electrical Engineering:
First, set the stage for the discussion and clarify some vocabulary. Information that expresses a single dimension, such as linear distance, is called a scalar quantity in mathematics. Scalar numbers are the kind of numbers students use most often. In relation to science, the voltage produced by a battery, the resistance of a piece of wire (ohms), and current through a wire (amps) are scalar quantities.
When electrical engineers analyzed alternating current circuits, they found that quantities of voltage, current and resistance (called impedance in AC) were not the familiar one-dimensional scalar quantities that are used when measuring DC circuits. These quantities which now alternate in direction and amplitude possess other dimensions (frequency and phase shift) that must be taken into account.
In order to analyze AC circuits, it became necessary to represent multi-dimensional quantities. In order to accomplish this task, scalar numbers were abandoned and complex numbers were used to express the two dimensions of frequency and phase shift at one time.
In mathematics, i is used to represent imaginary numbers. In the study of electricity and electronics, j is used to represent imaginary numbers so that there is no confusion with i, which in electronics represents current. It is also customary for scientists to write the complex number in the form a + jb.
Introduce the formula E = I • Z where E is voltage, I is current, and Z is impedance.
Possible Student Questions:
The impedance in one part of a series circuit is 2 + j8 ohms, and the impedance in another part of the circuit is 4 - j6 ohms. Find the total impedance in the circuit. Answer: 6 + j2 ohms
