A parallel plate capacitor has two plates, each of area3.0x10-4 m2, separatedby 3.5x10-4 m. The space betweenthe plates is filled with a dielectric. When the capacitor isconnected to a source of 120 V rms at 8.5kHz, an rms current of 1.6 x10-4 A is measured.
a) What is the capacitive reactance?
b) What is the dielectric constant of the material between the plates of the capacitor?
