QUESTION 1
The charge taken by a capacitor is 0.1 AC when terminal voltage is 35 V. The plate area of the capacitor is
31cm, and its dielectric thickness is 0.4 mm. Ɛn=8.85×10¯12F/m
Calculate the relative permittivity of the dielectric. (keep two decimal places)
QUESTION 2
A71 pF parallel-plate capacitor has the area of its plates halved and the distance between them increased four
times. What is the resulting capacitance? (unit:pF) (Keep two decimal places) (no need to key in unit)
