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

Fact 2: Electrical power in a circuit is equal to the product of the current and voltage in that circuit.

Given the two facts above, answer the question "electrical power does what when it runs through the circuit?" with the following options: 
- lowered energy cost
 - works properly
 - get started
 - power failure
 - breaks down
 - powers off
 - to move people
 - heat energy


 

  works properly
