# What characteristic of electricity is expressed in watts?

- the amount of work required to move electrons through a circuit
- the resistance to the flow of current in a circuit
- the amount of electrons flowing through a circuit per second
- the work required to move electrons through a circuit multiplied by the number of electrons flowing through a circuit per second

**Explanation:**Watts is the unit used to measure the electrical power. Power refers to the work required to move electrons through a circuit multiplied by the number of electrons flowing through a circuit per second.
