Condition :   Good   
Principle :   Household Electrical Measurement and Protectors  
Area of Study :  Electricity & Magnetism  
Equipment :   12 volt Car Battery, Thin Soft Wire (Fuse Wire) or Tin Foil.

Procedure :   A demonstration of a fuse is to take a length of the soft wire that is available and short directly across the 12 volt car battery. The wire will heat to a glowing red before it melts breaking the circuit. NOTE: The wire should be bent so that when it melts it does not fall on the instructors hands.
