|Ohm's Law & related equalities|
|E is electrical voltage potential in volts.
I is the flow of electrons in amperes current flows from the point of highest potential (negative) to the point of lowest potential (positive)
R is resistance to the flow of current in ohms.
Z is impedance to the flow of alternating current in ohms.
P is electrical power to do work in watts
|I=E/R R=E/I E=I*R
I=E/Z Z=E/I E=I*Z
E = P/I
I*Z square root of (P*R)
square root of (P*Z)
I = P/E
square root of (P/R)
square root of (P/Z)
R = E/I Z = E/I P/I**2 P/I**2 E**2/P E**2/P P = E*I R*(I**2) Z*(I**2)
