Question #183
Shown in the photograph below is a charged parallel plate
capacitor. Gwen is about to hold a match up so that its flame will be
located between the capacitor plates just below the plates, as seen.
What might happen to the voltage across the plates when the match is
brought near to the plates as shown?
When the match is brought near the plates, the voltage on the capacitor
will:
- (a) increase, due to the additional charge of the burning match.
- (b) decrease, due to the ions being drawn to the oppositely charged
plates.
- (c) nothing: flame is not attracted by charge.
