Understanding Capacitors

What is the formula for capacitance?

• C = Q*V

• C = V^2/Q

• C = Q/V

• C = V/Q

How is charge related to capacitance?

• Capacitance is independent of charge and voltage.

• Charge is equal to capacitance divided by voltage.

• Charge is inversely proportional to capacitance and voltage.

• Charge is directly proportional to capacitance and voltage, expressed as Q = C * V.

What is the energy stored in a capacitor formula?

• E = 1/2 * C * V

• E = 1/2 * C * V^2

• E = C * V^2 / 2

• E = C * V

How do you calculate the equivalent capacitance in series?

• C_eq = 1 / (1/C1 + 1/C2 + ... + 1/Cn)

• C_eq = C1 - C2

• C_eq = C1 + C2 + ... + Cn

• C_eq = C1 * C2 / (C1 + C2)

What is the equivalent capacitance in parallel?

• C_eq = C1 * C2 * C3 * ...

• C_eq = C1 + C2 + C3 + ...

• C_eq = C1 - C2 - C3 - ...

• C_eq = 1/(1/C1 + 1/C2 + 1/C3 + ...)

What effect does a dielectric material have on capacitance?

• A dielectric material decreases capacitance.

• A dielectric material has no effect on capacitance.

• A dielectric material increases capacitance.

• A dielectric material only affects resistance.

Can you name a common application of capacitors?

• Power supply filtering

• Signal amplification

• Energy storage

• Voltage regulation

What happens to the total capacitance when capacitors are connected in series?

• The total capacitance increases.

• The total capacitance decreases.

• The total capacitance becomes zero.

• The total capacitance remains the same.

How does the electric field behave between capacitor plates?

• The electric field is zero between the plates.

• The electric field direction is from negative to positive plate.

• The electric field is uniform and directed from the positive to the negative plate.

• The electric field is only present outside the plates.

What do electric field lines represent?

• Electric field lines show the mass of charged objects.

• Electric field lines represent the speed of electric currents.

• Electric field lines indicate the color of the field.

• Electric field lines represent the direction and strength of the electric field.
