Read this paragraph and choose the correct option from the provided answers:

20.2 Ohm’s Law: Resistance and Simple Circuits What drives current? We can think of various devices—such as batteries, generators, wall outlets, and so on—which are necessary to maintain a current. All such devices create a potential difference and are loosely referred to as voltage sources. When a voltage source is connected to a conductor, it applies a potential difference V that creates an electric field. The electric field in turn exerts force on charges, causing current.

 Choices:

- voltage

- output

- wattage

- current


A:
current
