# Displacement current and lamp

The changing electric field creates current and between the plates of a capacitor, there exists displacement current. I wonder what happens when a lamp put between the plates of capacitor with no electrical conducting path? Does it light up? I really need help and if you find demo videos etc. would be really good. Thanks.

• Can one run enough AC current trough a capacitor to power a lamp? Of course. The AC impedance of a capacitor is $Z=1/(i2\pi fC)$, i.e. it drops with frequency and capacitance and for many applications it can be made as small as a fraction of an $Ohm$. Apr 19 '16 at 7:29
• @Canbeck Is the lamp between the plates of the capacitor with no electrical conducting path to it or is it connected to the capacitor plates with metal wires? Apr 19 '16 at 7:37
• @Farcher I am sorry not to mension that. It is just put between the plates of the capacitor, there is no electrical conducting path between the lamp and the plates. Apr 19 '16 at 7:53
• OK, don't do this at home... but one can easily set fire to aluminum foil with a microwave oven... that's exactly what you want. Now that you know: don't. Watch someone else do it on YouTube. Apr 19 '16 at 7:54
