Electric Currents

• An electric current is a flow of electric charges.

5
A circuit is the path that is made for an
electric current.
6
Series Circuit

• A circuit that only has one path for current to
  flow through is called a series circuit.

7
If the path is broken, no current flows through
the circuit.
8
Parallel Circuits

• A type of circuit that has more than one path for
  current is called a parallel circuit.

9
If one part of the path is removed, the current
continues to flow through the other paths of the
circuit.
