voltage ( V ) – RENAISSANCE PHYSICS

INTRODUCTION TO ELECTRONICS: Power in Series Circuits

Thus far, we have seen how the net resistance ( R ) to current ( I ) flow within a series circuit is the sum of all the resistors that are present: Rt = R1 + R2 + R3 +…Rn The voltage ( V ) drop that occurs as a coulomb ( C ) ofContinue reading “INTRODUCTION TO ELECTRONICS: Power in Series Circuits“

INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 5 )

We are now ready to complete the Part 3 exercise using Kirchhoff’s Node and Loop Rules: Due to the presence of nodes at points C and E, differing current ( I ) values will be used to evaluate the voltage ( V ) drops that occur around each loop. There are three unique circuit pathwaysContinue reading “INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 5 )“

INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 4 )

Prior to completion of the previous lecture’s circuit problem, some additional practice identifying nodes and branches within a multi-loop circuit will be helpful: We begin our journey at the 3 V source located at the far-left side of the diagram. As the current ( I ) moves upward and to the right, we encounter ourContinue reading “INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 4 )“

INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 3 )

Thus far, we have used a single-loop series circuit to demonstrate the principles of Kirchhoff’s Loop Rule. What if, however, a circuit has multiple loops through which current ( I ) travels? To further complicate things, what if each loop contains a voltage ( V ) source? How will it be possible to determine theContinue reading “INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 3 )”

INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 2 )

The Loop Rule states that the sum of voltage ( V ) rises and drops around a closed loop must equal zero. This observation is an extension of the Law of Conservation of Energy which states that energy is neither created or destroyed, but it has the ability to change form. Furthermore, the direction thatContinue reading “INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 2 )”

INTRODUCTION TO ELECTRONICS: The Voltage-Divider Formula

Thus far, we have seen how the sum of voltage drops across a series circuit is equal to the voltage value of the source ( Vs ): Vs = V1 + V2 + V3 In the aforementioned scenario, three resistors are situated within a non-diverging electrical path; thus, each resistor along the electrical path hasContinue reading “INTRODUCTION TO ELECTRONICS: The Voltage-Divider Formula“

INTRODUCTION TO ELECTRONICS: Resistors in Series Circuits

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: Electron Volts vs. Kilowatt Hours ( Part 2 )

A previous mathematical derivation was used to determine that an electron volt ( eV ) is a quantity of energy carried by an electron that accelerates through an electric field. We will now see that the kilowatt-hour ( kWh ) is also a unit of energy; it is a quantum of energy carried by aContinue reading “INTRODUCTION TO ELECTRONICS: Electron Volts vs. Kilowatt Hours ( Part 2 )“

INTRODUCTION TO ELECTRONICS: Energy and Power ( Part 2 )

Newton’s First Law of Motion states that a body that sits still or moves with a constant velocity with respect to a motionless observer will have its status unaltered until acted upon by an unbalanced force. Such a change in motion is accompanied by an acceleration, which is a change of velocity of an object:Continue reading “INTRODUCTION TO ELECTRONICS: Energy and Power ( Part 2 )”

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”
