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

Fact 2: An electric charge in motion is called electric current.

Given the two facts above, answer the question "When a charge in motion runs through a circuit that signals that:" with the following options: 
- prevent heat loss
 - the charge is malfunctioning
 - depress neuronal excitability
 - heat is produced
 - the charge is working properly
 - water is generated
 - electron transport
 - the charge is turned off


 

     the charge is working properly
