The voltage ( V ) or “ potential difference “ of a DC power source is the drop in energy ( J ) that a coulomb ( C ) of charge will experience by traveling through a resistance ( R ) found within a circuit. The current in question flows along a closed, non-diverging route:Continue reading “INTRODUCTION TO ELECTRONICS: Resistors in Series Circuits”

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”
ELECTRONICS: Kirchhoff’s Laws
Q: What are the values of the currents ( I ) and unknown voltage drops ( V ) across the resistors ( R ) pictured below? A: The first problem-solving step involves assigning labels to the junctions ( j ) in the circuit: We must now sketch the currents flowing in the circuit: The currentContinue reading “ELECTRONICS: Kirchhoff’s Laws”
FORCE AND ACCELERATION: Mechanical Advantage and Tension Within Pulley Systems
The law of conservation of energy states that the total energy of an isolated system remains constant. The SI unit of energy is the joule ( J ), and it’s base-unit composition is kg*m2/s2. Energy is the currency needed to perform work, and work is performed upon an object when an applied force moves itContinue reading “FORCE AND ACCELERATION: Mechanical Advantage and Tension Within Pulley Systems”
