# 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 $Ohm$. – CuriousOne 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? – Farcher 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. – Canberk 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. – CuriousOne Apr 19 '16 at 7:54
