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: Kirchhoff’s Laws ( Part 1 )
Conventional current ( I ) within an electrical circuit travels from a positively charged anode to a negatively charged cathode terminal: In reality, electric field lines are what emerge from the positive terminal and terminate on the negative one; thus, negatively charged electrons actually flow in the opposite direction. Envisioning current as mobile positive chargesContinue reading “INTRODUCTION TO ELECTRONICS: Kirchhoff’s Laws ( Part 1 )”
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: Series Circuits
A series circuit is one in which electric current ( I ) travels along a closed path that does not split apart: *** Note: Conventional current consists of positive charges that flow from the positively charged anode to the negatively charged cathode. In reality, negatively charged electrons flow in the opposite direction. *** The diagram,Continue reading “INTRODUCTION TO ELECTRONICS: 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: Electron Volts vs. Kilowatt Hours ( Part 1 )
Although related, voltage ( V ) and power ( P ) are fundamentally different entities. The voltage within an electrical system is a measure of how many joules ( J ) of energy each coulomb ( C ) of charge ( q ) carries with it. Power is a measure of the rate at whichContinue reading “INTRODUCTION TO ELECTRONICS: Electron Volts vs. Kilowatt Hours ( Part 1 )”
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: Energy and Power ( Part 1 )
Although, energy and power are interrelated concepts, they possess distinct identities of their own. Consider the relatively simple task of inflating a balloon. Blowing a small puff of air into a balloon over a short time-interval will cause the balloon to expand slightly before recoiling to its previous state. Breathing more forcefully into a balloonContinue reading “INTRODUCTION TO ELECTRONICS: Energy and Power ( Part 1 )”
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”
