Learn how electric circuits work, the difference between series and parallel wiring, and the role of conductors and insulators.
An electric circuit is a closed path through which electric current flows, typically including a power source, wires, and a component like a bulb.
What happens if a circuit is broken (not closed)?
Current cannot flow, so the bulb or component won't work
Name one basic component of a simple electric circuit.
A battery (power source), wires, or a bulb
In a series circuit, components are connected in a single loop. In a parallel circuit, components are connected in separate branches, so each works independently.
In a series circuit, if one bulb burns out, what happens to the others?
All the other bulbs also stop working, since the circuit is broken
In a parallel circuit, if one bulb burns out, what happens to the others?
The others continue to work, since each branch operates independently
1. What is an electric circuit?
2. Name one component needed to complete a simple circuit.
3. In a series circuit, why does one broken bulb affect all the others?
4. Why are household appliances usually wired in parallel?
5. What is the function of a switch in a circuit?
