Fact 1: When an electrical circuit is working properly , electrical current runs through that circuit.

Fact 2: An electrical current is a flow of electrons.

Given the two facts above, answer the question "when a circuit is working properly, what runs through that circuit?" with the following options: 
- coils
 - direct energy
 - electromagnetic energy
 - conductors
 - h2o
 - activation energy
 - hydrogen and oxygen
 - flow of electrons
