Understanding Capacitors

What is the formula for capacitance?

• C = Q/V

• C = V/Q

• C = V^2/Q

• C = Q*V

How is charge related to capacitance?

• Capacitance is independent of charge and voltage.

• Charge is inversely related to capacitance by the formula C = V/Q.

• Charge is unrelated to capacitance and only depends on resistance.

• Charge is directly related to capacitance by the formula C = Q/V.

What is the unit of capacitance?

• ohm

• farad

• volt

• watt

How do you calculate the energy stored in a capacitor?

• E = C * V^2 / 2

• E = 1/2 * C * V

• E = C * V

• E = 1/2 * C * V^2

What is the formula for energy stored in a capacitor?

• E = C * V^2 / 2

• E = C * V

• E = 1/2 * C * V^2

• E = 1/2 * C * I^2

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

• The total capacitance decreases.

• The total capacitance remains the same.

• The total capacitance becomes zero.

• The total capacitance increases.

How do you calculate the total capacitance in series?

• 1/C_total = 1/C1 + 1/C2 + ... + 1/Cn

• C_total = C1 - C2 - ... - Cn

• C_total = C1 * C2 / (C1 + C2)

• C_total = C1 + C2 + ... + Cn

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

• The total capacitance decreases and is equal to the difference of the individual capacitances.

• The total capacitance remains the same as the smallest individual capacitance.

• The total capacitance is equal to the product of the individual capacitances.

• The total capacitance increases and is equal to the sum of the individual capacitances.

How do you calculate the total capacitance in parallel?

• C_total = C1 * C2 * C3 * ... * Cn

• C_total = 1/(1/C1 + 1/C2 + 1/C3 + ... + 1/Cn)

• C_total = C1 - C2 - C3 - ... - Cn

• C_total = C1 + C2 + C3 + ... + Cn

What is a dielectric material?

• A dielectric material is a type of magnetic substance that enhances magnetic fields.

• A dielectric material is a conductor that allows electric current to flow freely.

• A dielectric material is a liquid that can dissolve electrical components.

• A dielectric material is an insulating substance that can store electrical energy in an electric field.
