Reading Time: 13 minutesIntroduction Have you ever wondered how electricity goes into your electronic device, swirls around in there, and does something useful? Maybe you’ve thought to yourself, can I control that electricity? If so, how? First, let me tell you, that those questions are excellent, and to help guide you into how electricity is controlled — or […]
Reading Time: 19 minutesIntroduction Kirchhoff’s second law deals with the conservation of energy around a closed loop series path. We call this law Kirchhoff’s Voltage Law, or KVL, for short. What’s a Closed Loop Series Path? A closed loop series path is where there is a direct path through circuit elements from one point of the circuit around […]
Reading Time: 10 minutesIntroduction Kirchhoff’s first law deals with the conservation of charge entering and leaving a junction. We call this law Kirchhoff’s Current Law, or KCL, for short. What’s a Junction? A junction is where conductors in a circuit meet, then branch off in different directions within the circuit — kind of like an intersection in a […]
Reading Time: 9 minutesOhm’s Law is one of the most fundamental principles in electricity and electronics, and it’s what helps us to describe the relationship of the current through a conductor between two points in a circuit and its direct proportionality to the electric potential difference, or voltage across those two points. potential difference: the difference in electric […]
Reading Time: 13 minutesCircuit Element A circuit element refers to a basic component that is used to construct electrical circuits. The element can be a physical device or an abstract concept that exhibits specific electrical behavior and are combined together to form more complex circuits. These elements can include resistors, capacitors, inductors, and various other components that contribute […]
Reading Time: 8 minutesActive and Passive Elements Explained Recall that a source is any device that delivers energy into to a system. A source is a device that actively generates electrical energy, such as a battery — whereas, an electrical load is considered to be a device that passively extracts energy from a system, such as a speaker. […]
Reading Time: 11 minutesProject Name: The Chewing Gum Box LED Night Light Project Description: Learn to make a simple parallel LED circuit Project Difficulty: Easy Project Note: This project uses a soldering iron, but this is optional. See FAQs at bottom of page for alternatives. In this project, we’re going to make a battery powered LED night light […]
Reading Time: 6 minutesFor a circuit to be considered a series circuit, circuit elements within the circuit must have a direct path, each joined in sequence — and the current path never forking, branching or splitting off into a separate path. Simple Series Circuit If we are using conventional current flow (area of positive charge to area of […]
Reading Time: 9 minutesIntroduction Project Name: Simple Switch Circuit Project Description: Learn how to make a simple switch circuit. Difficulty: Easy In this project, we’re going to make the basic and simple switch circuit. Having a switch in your circuit allows you full control of your circuit. A switch allows you to turn ON or turn OFF the […]
Reading Time: 10 minutesTake a moment to think about any electronic device or piece of equipment containing electronics. There’s the coffee pot you use every morning, a smartphone you carry around in your pocket, the computer you use for work, a child’s battery powered toy, an electric car zooming down the interstate, robotic armatures welding together car parts […]
