plate

conductors

dielectric

terminals

A Capacitor

provide a specific value of capacitance

stores energy in a electrostatic field

opposes any change in voltage

all of the above

The amount of charge that a capacitor can accept is determined by

It's capacity C=Q/V

the plate area

all of the above

The two leads of the capacitor are connect to the

plates

terminals

conductors

dielectric

When a capacitor discharges

current reverses direction compared to the charge current

it acts like a DC open

the electrostatic charge remains

plate voltage increases

Capacitance is inversely proportional to

a charge

dielectric thickness

plate area

applied voltage

Capacitors well hold a charge until

the applied voltage drops to zero

5 time constants

an external discharge path is provided

1 time constant

conductive, conductive

insulating, conductive

insulating, insulating

12.

With respect to the capacitor, which relationship is true? •

C = Q×V

V = C×Q

V = Q/C

Q = C/V

13.

If C is the capacitance in Farads, ϵ permittivity of the dielectric, A area of plate overlap in square meters and d distance between plates in meters, then:

C = ϵd/A

C = A/ϵd

C = ϵA/d

C = d/ϵA

14.

Initially a capacitor stores 600 µC of charge. When it loses half of this charge, the potential difference (pd) across it decreases by 50 V. What is the capacitance of the capacitor?

1.5 µF

3.0 µF

6.0 µF

12 µF

15.

When capacitors is arrange in series (3 capacitors), the equivalent capacitance C is

C = C₁ + C₂ + C₃

1/C = 1/C₁ + 1/C₂ + 1/C₃

C = QV₁ + QV₂ + QV₃

C = CR₁ + CR₂ + CR₃
