Transcript of Electric Circuits
Second, the circuit has to be complete. If there is a break in the circuit, the current won't flow.
has only one path for electric charges to follow.
- a path along which electric charges can flow
An electric current needs two things to flow. First, it needs a source of current, or electrons.
A switch controls the flow of current by opening and closing the circuit.
This happens whenever we turn lights on or off!
Removing any part of the circuit breaks the circuit, and nothing works.
A circuit with several different paths for the charges to follow is called a
In a parallel circuit, if one part is turned off or removed, current continues to flow through the rest of the circuit.
This makes a parallel circuit more practical to use than a series circuit.
