Electrical circuits provide an uninterrupted path for current travel and are broken into two distinct categories of design: series circuits and parallel circuits. Electrical circuits consist of the following components: an energy source to provide voltage, conductors to allow current travel, insulators to limit current travel, and a load. Understanding the relationship between current, voltage, and resistance allows engineers to design efficient, safe, and functional electrical circuits. Resistance is the opposition to the flow of current. Voltage is the amount of work required to move a charge from one point to another. Current is the net transfer of electric charge per unit of time. Regardless of the conversion process, electrical energy consists of three basic components: current, voltage, and resistance. Electrical energy, depending on geographic location, is converted from mechanical energy, chemical energy, light energy, and thermo energy before it reaches the consumer. Today’s consumer utilizes electrical energy in all aspects of life, from cell phones and computers to refrigeration and heating and cooling systems, and even transportation. In the 21st century, electrical energy production, distribution, and application have become consumer driven. Activity 1.2.3 Electrical Circuits – Simulation Introduction Since the late 1800s, engineers have designed systems to utilize electrical energy due to its ability to be converted, stored, transmitted, and reconverted efficiently into other forms of energy.
