CAPACITOR AND LIGHT BULBS


APPARATUS

6 V battery
202-02-D1
three 6 V bulbs in sockets 202-19-E3
1 F 5 V capacitor 202-19-E2
switch 101-09-C2


DESCRIPTION NOTES
The bulbs are nonohmic so this is not a good quantitative demonstration.  The bulb resistance is about 40 ohms at 6 V, so two or three in parallel are used to speed things up a bit.  A (very nonohmic) bicolor LED can be used in parallel with the incandescent bulbs to show the direction of the current.
