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.

An electric circuit contains an operating heating element and a lit lamp. Which statement best explains why the lamp remains lit when the heating element is removed from the circuit? 

• The lamp has less resistance than the heating element.
• The lamp has more resistance than the heating element
• The lamp and heating element were connected in parallel.
• The lamp and heating element were connected in series.

A circuit is shown below. Which of the following is true of this circuit?

• It is series and therefore both resistors have the same voltage
• It is series and therefore both resistors have the same current
• It is parallel and therefore both resistors have the same voltage
• It is parallel and therefore both resistors have the same current
