Fuse Demo

From UO Physics Demonstration Catalog

Return to Resistance, EMF, and Current

Description:

Three light bulbs are hooked up in parallel with a piece of Nichrome wire as a fuse in series with the bulbs. Screw in the bulbs one at a time. The bulbs are set such that when the third bulb is screwed in, the Nichrome wire fuse burns up all the bulbs go out. SAFETY!! once the wire burns up, BE SURE TO DISCONNECT THE POWER since the terminals that held the Nichrome wire will now have 120V across it!!!
