Electric Circuits
⭐ MasteredAn electric circuit is a loop that lets electricity flow from a battery, through wires and components, and back again. A break in the loop stops the flow.
Your house has many circuits that carry electricity to every room.
All about Electric Circuits
An electric circuit is a closed loop that lets electricity flow from a power source, such as a battery, through wires and components and back to the source. If the loop is broken, the current stops.
Switches open and close the loop, which turns devices on and off.
Components such as bulbs, motors and buzzers use the electricity to do a job.
Circuits can be connected in a series, where everything is on one path, or in parallel, where each component has its own path. In a parallel circuit, if one bulb goes out, the others can keep shining.
