A level electrical current

An electric circuit that has more than one loop that the current can flow around.

The energy needed to push the electrons through part of a circuit.

A component who’s resistance depends on the light level.  The brighter the light the lower the temperature.

) What would happen if an extra battery cell is added?

• A)The lights will glow dim
• The wire will glow
• The lights will glow brighter
• None of the above

How many variables should be changed in an experiment?

• one
• two
• none
• all of them

What is an electric current? 

• the flow of electricity 
• electricity moving in only one direction
• a switch that gives power
