What is current measured in?

• Ω (Ohms)

• V (Volts)

• W (Watts)

Define electric current.

• It is the work done by the source in driving charges around a complete circuit.

• It is a measure of the rate of flow of electric charge through a given cross-section of a conductor.

• It is the work done by the source in driving a unit charge around a complete circuit.

• It is a measure of the flow of electric charge through a given cross-section of a conductor.
