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

question 11

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)0.50
• C)2.0
• D)4.0
• E)8.0
