Fun Fact
The longest-lasting light bulb in the world has been burning continuously for over a century! Known as the Centennial Light, this extraordinary bulb is located at a fire station in Livermore, California, USA. It was manufactured by the Shelby Electric Company around 1901 and has been illuminating the fire station almost uninterrupted since then. There is a picture of the light bulb below.
Key terms
Series Circuit is a type of electrical circuit in which components are connected sequentially along a single pathway, creating a single closed loop for the flow of current.
Parallel Circuit is an electrical circuit configuration in which components are connected across multiple pathways, allowing for multiple branches for the flow of current, each with the same voltage across them.
Conservation of Charge means that the total amount of electric charge entering a junction in a circuit equals the total amount of electric charge leaving the junction, ensuring a continuous flow of current throughout the loop without accumulation or depletion of charge.
Kirchhoff's Loop rule also known as Kirchhoff's voltage law (KVL), states that the sum of the voltages around any closed loop in a circuit must equal zero, accounting for both the voltage sources and voltage drops due to components in the loop.
Equivalent Resistance refers to the single resistance value that can replace a complex network of resistors in a circuit while maintaining the same overall resistance.
