Circuit Basics
What is a Circuit?
A circuit is a closed loop that allows electricity to flow from a power source, through components, and back again.
Conductors vs Insulators
Conductors let electricity flow through them freely, while insulators block or resist the flow of electric current.
What is Polarity
Polarity refers to the positive (+) and negative (−) ends of a power source, which determine the direction electricity flows in a circuit.
What is a Short Circuit
A short circuit happens when electricity takes an unintended shortcut between two points, bypassing the components it was meant to power.
How to Use Components
Power Supplies
A power supply provides the electrical energy needed to power all the components in a circuit
LEDs
LEDs are small lights that glow when electricity flows through them in the right direction
Motor
A motor converts electrical energy into movement, making things spin or turn
Switch
A switch controls the flow of electricity in a circuit by opening or closing the connection
