Title:
Description:
Demonstrates that an induced current can be stored in a capacitor.
Equipment:
1. Capacitor
2. Iron core coil (in box w/ EM-J-FE)
3. 2 B-A leads
4. 2 B-B leads
5. Edison cell battery
Procedure:
1. First connect the BA leads to the coil and one alligator end to the battery. Touch the other alligator end to the opposite end of the battery and observe the spark.
2. Connect the capacitor into the circuit as shown. Again touch the alligator end to the battery and observe how the capacitor has absorbed the charge, thus reducing the spark.
