MATHEMATICS: Radius, Radians, Diameter, Circumference, and ” Pi ” = 3.14

C = 2πR.  What does this mean?  What is its usefulness?  C = The distance around any circle.  But where did such a formula come from?  Start by drawing a circle.  Within the middle of the circle, draw a dot.  Now, draw a line that passes through the dot.  This line should divide the circleContinue reading “MATHEMATICS: Radius, Radians, Diameter, Circumference, and ” Pi ” = 3.14″

ELECTRICITY: Direct Current and Parallel Resistors

INTRODUCTION TO DIRECT CURRENT ( DC ) ELECTRONICS : Note: Assuming each resistor ( R ) = 64 Ohms, what is the equivalent resistance of the circuit from points A to B ? Symmetry regarding the flow of electrons is the key to calculating the total resistance ( R ) of this circuit. Let’s suppose theContinue reading “ELECTRICITY: Direct Current and Parallel Resistors”

MATHEMATICS: Binary Math and Digital Electronics

Write the numbers 8,4,2, and 1 in descending order.  We will form binary numbers by choosing the numbers from this list that are needed to form the binary number wanted.  Below, we will see how we use the number 1 to choose which number out of the ( 8,4.2,1 ) sequence is being used toContinue reading “MATHEMATICS: Binary Math and Digital Electronics”

ELECTRICITY: Kirchhoff’s Rules and Negative Current Values

Voltage, where V = IR, is the product of the current ( I ) of Amperes in an electrical circuit in units of coulombs per second ( q/s ), and resistance ( R ) in Ohms. Likewise, voltage is defined as the amount of energy in Joules ( J ) a coulomb of charge carriesContinue reading “ELECTRICITY: Kirchhoff’s Rules and Negative Current Values”

MATHEMATICS: Is The Earth Really Round?

Disclaimer: The earth, according to current mathematical models and observations, is not flat. ROUND-EARTH MATHEMATICS : In determining the rotational speed of the earth, we must first assume that the sun is positioned an exceptionally far distance from the earth.  If this were not the case, snow, water, and complex biological life would be non-existent.Continue reading “MATHEMATICS: Is The Earth Really Round?”
