A light bulb and a parallel plate capacitor (including a dielectric material between the plates) are connected in series to a 100 V AC source. If the dielectric between the plates is removed, then :
Options:(select one or more)
Answer:
A, B, D
Solution:
Removing the dielectric decreases the capacitance .
increases, so the impedance of the circuit increases.
decreases.
Hence the brightness of the bulb decreases.
