INTRODUCTION TO ELECTRONICS: Ohm’s Law

The graph of a straight line represents a proportional relationship between input variables and output values; with every increase ( or decrease ) in input values, a proportionate change in output can be expected. The graph of a straight line can be graphed via usage of the following formula: y = mx + b ForContinue reading “INTRODUCTION TO ELECTRONICS: Ohm’s Law”

INTRODUCTION TO ELECTRONICS: Metric Prefix Conversions ( Part 2 )

The number 1 can be formed via the establishment of a ratio of logically related quantities: A = A ( A / A ) = 1 A = B ( A / B ) = 1 And, ( B / A ) = 1 Furthermore, the product of any number multiplied by 1 is theContinue reading “INTRODUCTION TO ELECTRONICS: Metric Prefix Conversions ( Part 2 )”

INTRODUCTION TO ELECTRONICS: Metric Prefix Conversions ( Part 1 )

The process by which metric prefixes are converted from one value to another is based upon the following premise: 1 x 1 = 1 This premise can be easily applied to statements of truth that involve variables: a = a ( a / a ) = 1 b = b ( b / b )Continue reading “INTRODUCTION TO ELECTRONICS: Metric Prefix Conversions ( Part 1 )”

INTRODUCTION TO ELECTRONICS: Electrical Quantities and their Corresponding SI Units

The International System ( SI ) has established internationally accepted values for physical quantities. These agreed-upon values constitute the building blocks of many scientific fields of study, including electronics. Each quantity in question is accompanied by a symbol, and each symbol can be substituted with an SI unit that gives it meaning. Consider the followingContinue reading “INTRODUCTION TO ELECTRONICS: Electrical Quantities and their Corresponding SI Units”

INTRODUCTION TO ELECTRONICS: Electrical Units and Metric Prefixes

Physical realities would be meaningless without internationally standardized definitions that quantify their existence. Within the field of electronics, there are electrical units of measure that are so common that becoming familiar with them is highly advisable for new students. It is important to note that the aforementioned electrical phenomena occur in measured quantities that areContinue reading “INTRODUCTION TO ELECTRONICS: Electrical Units and Metric Prefixes”

INTRODUCTION TO ELECTRONICS: Scientific and Engineering Notation

Within the observable universe, measurements ranging from “ very small “ to “ very large “ can be made. The rules of scientific notation enable such measurements to be expressed in convenient powers of ten. In order to express a number in scientific notation, a number that does not fall between the numbers 1 andContinue reading “INTRODUCTION TO ELECTRONICS: Scientific and Engineering Notation”

INTRODUCTION TO ELECTRONICS: Direct Current ( DC ) Voltage, Current, and Resistance

An introductory discussion of electronics would be remiss without a conceptual analysis of DC voltage ( Vdc ), current ( I ), and resistance ( R ). Most students readily adapt to teaching strategies that relate new topics to familiar themes and everyday life experiences. Visual aids are of preeminent importance to new and seasonedContinue reading “INTRODUCTION TO ELECTRONICS: Direct Current ( DC ) Voltage, Current, and Resistance”

AP PHYSICS: Graph-Slope Interpretation

Consider the following graph: If we allow the ( y1 ) and ( x1 ) coordinates of the slope formula to be zero, a predictable slope begins to emerge as we move to the right. A steeper slope would necessitate a greater change in y-values relative to corresponding changes in x-values. Likewise, a less steepContinue reading “AP PHYSICS: Graph-Slope Interpretation”

AP PHYSICS: Conversion Fractions

If we multiply the number 1 by a unit A, we end up with one unit of A: 1 x A = A We are at liberty to substitute A with any quantity we wish: 1 x 5kg = 5kg 1 x 6s = 6s 1 x 100m = 100m Furthermore, 1 x A =Continue reading “AP PHYSICS: Conversion Fractions”

AP PHYSICS: Scientific Notation

It would be extremely inconvenient, inefficient, cumbersome, and annoying ( if even possible ) to make measurements of submicroscopic life forms and cross-continental terrain with the same instruments. Scientific notation provides us with a condensed method of expressing both large and small quantities alike. In addition to convenience and practicality, scientific notation reduces the chancesContinue reading “AP PHYSICS: Scientific Notation”
