Understanding Capacitor Configurations

What is the total capacitance of two capacitors in series, each with a capacitance of 4 µF?

• 2 µF

• 1 µF

• 8 µF

• 4 µF

In a parallel capacitor configuration, how do you calculate the total capacitance?

• 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

If three capacitors of 2 µF, 3 µF, and 5 µF are connected in series, what is the total capacitance?

• 4 µF

• 2.5 µF

• 1.5 µF

• 0.968 µF

What is the formula for calculating the energy stored in a capacitor?

• E = C * V

• E = 1/2 * C * I^2

• E = 1/2 * C * V^2

• E = C * V^2 / 2

How does the voltage across capacitors in series compare to the voltage across capacitors in parallel?

• The voltage across capacitors in parallel is divided among them.

• The voltage across capacitors in series is always higher than in parallel.

• The voltage across capacitors in series is divided among them, while in parallel, it is the same across all capacitors.

• Capacitors in series have the same voltage across them as in parallel.

If a capacitor stores 10 joules of energy and has a capacitance of 5 µF, what is the voltage across it?

• 50 volts

• 2000 volts

• 100 volts

• 500 volts

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

• The total capacitance becomes zero.

• The total capacitance increases.

• The total capacitance remains the same.

• The total capacitance decreases.

In a series configuration, how does the charge on each capacitor compare?

• The charge on each capacitor is the same.

• The charge on each capacitor is different.

• The charge on the last capacitor is zero.

• The charge on the first capacitor is the highest.
