An electric circuit is a closed loop that allows electric current to flow through components like batteries, bulbs, switches, and connecting wires.
A battery converts stored chemicals into electricity, providing a voltage that drives the electric current. It has positive and negative terminals and needs replacement or recharging when depleted.
An electric bulb features a filament that glows when current heats it. If the filament breaks, it disrupts the circuit and the bulb stops functioning.
Connecting Wires
Made of conductive metals like copper or aluminum, wires carry electric current. Insulated to prevent leakage, any gap in the wires makes the circuit incomplete, stopping device operation.
A switch controls the circuit by opening or closing the path for current. A resistor limits current flow and controls resistance within the circuit to regulate functionality.
Series circuits have components connected in a single path, so if one fails, the entire circuit stops. Parallel circuits offer multiple paths, so failure in one path doesn’t affect others. For more help with circuits, visit eTutorWorld.com for expert tutoring and resources.
