Comment faire comment fabrique comment creer Let’s Abuse a Battery!
To get a better feeling for electrical power, you’re going to do what most books tell you not to do. You’re going to short out a battery. A short circuit is a direct connection between the two sides of a power source.
You will need:
• 1.5-volt AA battery
• Single-battery carrier
• 3-amp fuse
• Safety glasses (regular eyeglasses or sunglasses will do)
Procedure
Use an alkaline battery. Do not use any kind of rechargeable battery. Put the battery into a battery holder that’s designed for a single battery and has two thin insulated wires emerging from it, as shown in Figure 1-32. Do not use any other kind of battery holder. Use an alligator clip to connect the bare ends of the wires, as shown in Figure 1-32. There will be no spark, because you are using only 1.5 volts. Wait one minute, and you’ll find that the wires are getting hot. Wait another minute, and the battery, too, will be hot
