12. What happens when an electric
current is produced?
• a continuous flow of charges
travel through a material
13. Contrast electric current and
static electricity.
• An electric current is a
continuous flow of charge.
In static electricity, charges
build up but do not flow.
14. Explain why electric current
cannot exist if an electric circuit is
broken.
• charges cannot flow because
the path is not complete
15. Define conductor and insulator.
• conductor = material through which
charges can flow through easily
• insulator = material through which
charges cannot flow through easily
