An Air-Filled Parallel-Plate Capacitor Has a Capacitance of 1 PF

Multiple Choice

An air-filled parallel-plate capacitor has a capacitance of 1 pF. The plate separation is then doubled and a wax dielectric is inserted, completely filling the space between the plates. As a result, the capacitance becomes 2 pF. The dielectric constant of the wax is:

A) 0.25
B) 0.5
C) 2.0
D) 4.0
E) 8.0
